Garth Nix

236 books14.9k followers
Garth Nix was born in 1963 in Melbourne, Australia, to the sound of the Salvation Army band outside playing 'Hail the Conquering Hero Comes' or possibly 'Roll Out the Barrel'. Garth left Melbourne at an early age for Canberra (the federal capital) and stayed there till he was nineteen, when he left to drive around the UK in a beat-up Austin with a boot full of books and a Silver-Reed typewriter.

Despite a wheel literally falling off the Austin, Garth survived to return to Australia and study at the University of Canberra. After finishing his degree in 1986 he worked in a bookshop, then as a book publicist, a publisher's sales representative, and editor. Along the way he was also a part-time soldier in the Australian Army Reserve, serving in an Assault Pioneer platoon for four years. Garth left publishing to work as a public relations and marketing consultant from 1994-1997, till he became a full-time writer in 1998. He did that for a year before joining Curtis Brown Australia as a part-time literary agent in 1999. In January 2002 Garth went back to dedicated writer again, despite his belief that full-time writing explains the strange behaviour of many authors.

He now lives in Sydney with his wife, two sons and lots of books.

This series is not as good as Garth Nix's other works, but it's also aimed at a much younger audience, so perhaps that explains it. We see more from our two young heroes as they continue to try to recover a magical artifact. Similar to the last book, it felt like it just ended at an unnatural point.

I love Garth Nix's books. He's really good at quickly building up a world that has enough detail for you to know roughly the rules you're playing by, and what's going on, without telling you everything in a massive infodump. Aenir advances the plot without giving too much away: I haven't guessed the end, as I so often do with books.

It's also a really quick read. I'd be happy with more detail, more character development, but it's pretty fun as it is -- unfortunately, I don't have much to say about the way it is. It's aimed, I think, at younger kids than Nix's other stuff: it's more simplistic. But it still keeps my interest, too (and I'm arguably an adult, whatever my parents think!).

It's funny: I vaguely remember being so excited as a kid to read this book because "ERMERGERD AENIR!" But today, as an adult, I have to admit that, even though I absolutely loved the first two books of the series, this one... is just bad.

The main problem is the tone. The series so far has kept a serious, dark tone with dashes of whimsy and fun. And then AENIR: an entire book of silly, cute plot points in a silly, cute world. This book felt more like PHANTOM TOLLBOOTH than a Seventh Tower entry.

Adding to this problem were all the new characters we meet in AENIR. They were all annoying, one-dimensional creatures that gave us nothing but impatience and stilted dialogue. Mainly, two Storm Shepherds that should be awesome in theory, but Nix instead decided to make them comic relief by making them whine and complain a lot. While I can appreciate what he was trying to do, it did NOT work out as well as the actual TALKING EYEBROW in his Keys to the Kingdom series. Yup. That's a thing.

Speaking of Keys to the Kingdom... another new character is this talking lizard with a deep voice that says very serious things, and is sometimes controlled by the Codex, an all-knowing compendium of knowledge. Sound familiar? Keys to the Kingdom, another fantasy series for children by Garth Nix, featured a frog with a deep voice that said very serious things, and was controlled by the Will, the all-knowing last will and testament of the entire universe.

Another big problem I had with AENIR was the "chapter must end in cliff-hanger!" compulsion Nix obviously had while writing this book. There was literally a chapter that ended with the protagonist saying, "Oh, no! I lost that thing that's crucial to the plot!" and then the very next chapter starting with the protagonist saying, "Oh, wait, never mind, it's right here." WHAT. NO. STAHP. That's just... horrendous.

Unfortunately, I had to change my original 5-star rating. I couldn't put it below a 3-star, though, because I still love the series The Seventh Tower. Just not this book.

Here's to a better #4.

Hmm. This book incorporates the spirit world of Aenir into the setting, bringing to life the concepts Nix introduced in the first two books in the Seventh Tower series. What I like about this is that there are deeper levels to his story, or his message if you will, in this book. It offers a mature, could-be-studied-in-English-class aura to a much younger audience. Readers can look at Tal's experience and question what they believe to be reality. They can consider what it really means to escape your reality and substitute another, sometimes dangerous, reality. And don't forget the troubles that can be started by evil entities taking a position of power over the masses. Oh and stir in an oppressive caste society to add some flavor.

Great book to be enjoyed by all. Another 4 stars.

   Tal may have found Sunstones for him and Milla now, but his brother Gref is missing, his mother in a coma, and his only hope to help them and save his family is to find the lost Codex of the Chosen which lists all the Shadowspirits and their masters. But the Codex has been hidden in Aenir, the world where the Chosen bind their Shadowspirits from, a world of strange creatures, rules, and danger and death lurking around every corner. Tal and Milla will have their fledgling trust in each other put to the test, if they can even survive the creatures and blood-price rules of Aenir.
   Maybe partly due to how I read this book across two days, in essentially two sittings, but it never slowed down. It was one thing after another, surprise after revelation. We not only saw a huge test of the trust growing between Milla and Tal, but also the fallout when that trust is broken. In the previous book we started getting small glimpses from Milla’s point of view, and here we get much more, as her and Tal split up in Aenir. Sometimes a little distance helps with perspective, and Aenir offers as much distance as either could ask for. But it also means that Tal will miss having Milla’s fighting skills, and Milla will lack having Tal’s knowledge about Aenir and its creatures.
   Their new Storm Shepherd companions can offer some assistance, which may be welcome or not depending on the situation. Adras and Odris have rather simplistic personalities, but that makes it very clear for young readers what their strengths and weaknesses are, and how they may be an asset or a hindrance to Tal and Milla. Aenir itself is quite the world to find oneself in, and offers no end of unusual and more often than not unpleasant surprises.
   Not to mention Nix unspools a little more of the lore and history, as well as the secrets, of the Dark World Tal and Milla come from, Aenir, the Veil, and the war that brought about the separation of the worlds and the Forgetting and Binding in Aenir. This installment builds momentum, and pushes Tal and Milla to empathize even more with one another even as their cracked trust comes between them.

When reading this book now compared to my youth one sees how their opinion changes. In my youth I assumed Milla to be a tough-cookie who I would love to have a relationship with. Now I find her abrasive and entitled. Tal is constantly required to change his view on the world but at the some time no one seems to respect what his beliefs. I find it weird that he has to sacrifice everything and just has to take it but when Milla does it, oh I am a victim the world sucks. Its weird that we commend Milla's growth but Tal's is just required, that's how it comes across to me.

It is a pretty short read. I finished reading the first 3 books in one day. It is a fun read, the anticipation of what is going to happen next is there but the characters (Tal and Milla) seemed to have little to no development. I am not talking of romantic feelings but their overall perception of the things happening. I know they both have different goals (and feel strongly to attain it) but they were aware of something bigger happening, and yet they don't seem to care. But the are still 3 more books to read so I can't really judge the whole series yet.

A decided uptick in quality from the first two installments, but still not my favorite series from Garth Nix.

The world being slowly revealed continues to be fascinating and many-layered, and now Nix is weaving in a complex past history for our heroes to grapple with along with their present-day problems. The plot seems to be rushing towards a grand battle to decide the fate of the world, which is always stimulating.

However, many of the irksome tendencies from the first two books are still present in this book. Though Milla and Tal have finally stopped loathing each other in every sentence (finally!) the plot too often continues to rely on one or the other of them holding an idiot ball to keep moving. Failing that, they have each gained a new companion who can be trusted to catch the idiot ball if either of them drop it. They succeed through the divine intervention of fate, the gods, and the benevolent Garth Nix rather than any intrinsic worth or good decision-making on their parts. This is a frustrating way to experience the plot, with one silly coincidence after another either impeding them or helping them on their way.

This is shaping up to be an interesting world with a dramatic climax, if nothing else, and this middle book did have some great character moments to show that Milla and Tal are actually learning from each other. I would be happier if Nix seemed likely to allow their actions to affect the plot, but I guess one can't have everything.

[Short and quick review from memory before I re-read and re-review at a later date:

Absolutely no memory of this book or the series as a whole, really. Maybe some vague stuff... but really no. Definite re-read, along with the rest of the series.]

Tal of the Chosen and Milla of the Icecarls find themselves in the spirit world of Aenir, where rivers and trees move daily, and even the most solid mountains can lift themselves off the earth, on a mission to find the all-knowing Codex to help Tal save his family and help Milla find her way back to her people. To increase their chance of survival, Tal decides to teach Milla how to properly use her sunstone and in exchange, Milla will teach Tal how to physically defend himself Icecarl-style. They then re-enact the blood-promise ritual, which unbeknownst to them, conjures up Adras and Odris - two sibling Storm Shepherds - who were bound to Hrigga Hill. In accordance to this binding, the two, when called upon by blood, must give a gift to the summoner in exchange for a life.

Tal believes that the only way to save them is to bind the Storm Shepherds to them as Spiritshadows, but that would mean Milla could never become a Shield Maiden as they are sworn to destroy all animated shadows. Tal begins performing the ritual. Milla, who would rather die than be disgraced grabs her Merwin sword…

How will they get out of this bind and will they find the Codex?

Aenir (Book 3 of The Seventh Tower series) takes us on a magical journey into the spirit realm of Aenir. We learn a little more about the history of this world and the roles that each of the factions (Shadow-wielding Chosen, Nomadic Icecarls and Aenirans, creatures of Aenir that turn into shadow when they enter the Dark World). We also learn about a war that happened thousands of years prior and that the Veil came into being in the aftermath of the war.

The book ends on a cliffhanger… again. And as usual, Tal’s aunts - Lallek and Korrek - are mentioned as the cousin’s of Tal’s mother, then later referred to again as Tal’s cousins. It's just getting old. They’re either his AUNTS or his COUSINSCHOOSE! Now I’ve heard the “I’m my own Grandpa” song, and to be honest, it made perfect sense. If Garth could actually be kind enough to point out how Lallek and Korrek can be both Tal’s mom’s cousins and Tal's cousins as well, that would be great.

In general, it was a good read. There was a bit more character growth/development. Milla being the more logical of the two, has slowly learned to accept her fate and move forward. Tal's slowly learning to put himself in other people’s shoes tries to understand them better.

Looking forward to Book 4 - Above the Veil.

It kind of started at the end of the last book and so they go into the castle and they meet Ebbit and then guards come and they take Milla. Then Tal and Ebbit have to go save her from the hall of nightmares which is supposed to be the scariest thing there but Milla can't be affected by it because she has the crones to protect her. Then they go to Aneir and try to save the codex.
How to make a friend that want's to kill you. First, you want to bind your blood together on a quest so then the friend can't kill you. Then you save their life. After that, you go on another quest to another dimension and then bind your blood again to make 2 storm shepherds appear. Then trade their normal shadow with the storm shepherds shadow to accidentally make them mad. Then run away and try to face an angry Horzax. Finally get a codex to possess an animal and save their life and blackmail them to help you save the codex. (The burning tower) Finally, save the codex and return home. Then try and save your brother that was captured by an evil person. Then escape to where no guards would go. Then get caught.
I liked this book because of all the animals that are in it and how many creatures that are made up in all of the books. I also liked the book because of all the crazy things that happened and some of the funny and scary parts. I also liked the other series and I plan to read the rest I am already starting the fourth book and I just finished the third. I just liked the book

Tal and Milla are both stuck in Aenir now, where ferocious creatures can find them easy prey. But they went to Aenir to find the Codex, a device that can provide answers to their mission goals. At the same time, two beings, known as Storm Shepherds, prepare to square off against the two children. But through Tal's own ingenuity, these Storm Shepherds become his and Milla's new shadows. Unfortunately, tension rises between the duo and they split, fending for themselves against an unnatural realm where anything can pose a danger.

Just like Castle, Aenir picks up where the cliffhanger ended and resumes with minimal issues. But I found Milla to be a character relatively harder to like, as her headstrong attitude makes her formidable, but clashes frequently with Tal. Also, the Shepherds who started out as potential threats to Milla and Tal, once they become their shadows; their personality became a little more campy. While that's not too bad, it feels like things took a left turn for these two beings as well. And while the setting is reasonably developed, the story mostly focuses on Aenir, but as soon as they return to the castle, that is where I felt like the plot was straying and I gradually lost interest by the last few pages. Now I know this book is written for a slightly younger audience, but I do hope the sequel holds up better with how it ends than here.

Aenir is the third book in Nix's Seventh Tower Series. In the magical world of the Aenir, Tal and Milla must navigate both the hostile environment and each other to find the Codex.

I found the shadow bounding between Tal/Milla and Adris/Odris really fascinating. Adris/Odris serve as a foil to Tal/Milla, representing either recklessness or calculation, the trait that is at most antithesis to the paired character, and remains so for the rest of the series.

For being in a magical realm, I felt like I was tantalized with aspects of the world, but never given great depth into them. Maybe that is on purpose, as the residents of Aenir have lost their memory at what happened before the war. Still, parts of Milla's journey was unfulfilling, as her adventure essentially experiences a Deus ex Machina and the resolution to her entrapment in the tower was unsatisfying. Tal, at least, has a much more fleshed out narrative through this book.

I would probably give this a 3.5 stars, if I could. I enjoyed seeing another aspect of the world, but felt that Milla's narrative was weaker than Tal's.

Tahle série se čte prostě úplně sama. Ráno knihu otevřu, když jedu do práce, a večer, když jedu z práce, ji zase dočítám. Obsahem třetího dílu je zase jiný svět, než ten Temný. Celý děj se odehrává ve světě duchů Aeniru, kde svítí slunce a střídá se den a noc, protože tu žádný závoj není. Ohledně toho mě bavilo, jak byl svět nebezpečný. Na každém rohu číhala nějaká potvora, která chtěla hlavní hrdiny sežrat. Taky mě zajímala válka mezi Aenirem a Temným světem, o které se tu hrdinové dozvěděli. Ne vždycky byli Vyvolení a Ledované odděleni.

Z postav se mi tu nejvíc líbili jednoznačně oba hřmotní pastýři, kteří se pak stali duchostíny Tala a Milly. Ti byli hrozně vtipní, jak byli neohrabaní a měli trošku pomalejší vedení. Tal s Millou se tu zase o něco víc hádali, protože Tal Mille vlastně zničil její budoucnost. Ale ty jejich rozepře byly někdy dost vtipné a ještě když se k tomu přimotali oba pastýři. To jsem se často smála.

Konec je opět hrozně otevřený, jak už je u téhle série zvykem, ale nijak zvlášť mi to nevadí, když mám všechny díly po ruce.

My least favourite parts of the previous two books was Tal’s uncle Ebbitt, whose silliness clashes with the more serious tone of the book (yes I know it’s a kids book, but still). This third instalment of the series focuses more on this silliness as the characters explore the magical and oftentimes nonsensical world of Aenir.

I quite liked how Milla was an equal focus to Tal in this book, and preferred her segments over Tal’s. Tal’s pretentiousness is lessening with each book, which is also a nice touch as he starts off rather unlikeable, glad to see that was the author’s intention!

The two storm shadows were probably the worst additions, especially Adras whose (repeatedly mentioned) ‘lack of intelligence’ can come across as ableist at times. You can make a “stupid” character without making them act childish or have it be their entire personality.

Definitely a step down this book. The later book(s) seem to not be in Aenir, so hopefully things return to normal.

One of the more interesting books thus far. I thought the lore behind Aenir was unique and interesting, and I liked the way that the story is unfolding. We are learning more about the history of Aenir and the Dark World as the character learns it, and I like stories where the reader only knows what the character knows. The creatures were imaginative and kinda terrifying and the way he created such a uniquely dangerous world was just so interesting. I remember the burning tower where Mila and Odris landed and basically once you're on or in the tower you can't escape and once the sun rises the tower starts on fire and you die, which is quite inventive. The magic in Aenir is really cool, and I think number 3 is my favorite so far. I also appreciate that Tal isn't so much of a baby anymore.

This is a story that takes me back to my youth. I remember when I had dreams after reading book six, feeling like I was in the world. Garth Nix builds a very captivating world, and I finished reading this series for the second or third time right after I graduated from university with a BA. In this world, there are two groups of humans. One group lives in a castle and there is a heirarchy of lower class citizens who don't have mastery over light and higher ranked people who have magical stones that allow them to wield different colors of light, and there is another group of humans that live out on the ice.

Still really enjoying this series!

I actually thought the way Aenir was set up was really creative, and I liked the twist with Milla a lot. I particularly liked the weirdness of the world, the way it didn't follow normal rules, and particularly the darker aspects like Milla's tower and Tal's meeting with Hazror.

Definitely looking forward to more puzzle pieces falling into place, and finding out what's going on with Sushin.

I feel really let down by this book. The first two books were awesome... and then we get the third book, Aenir. I feel like the author tried to be funny and make this light heart but instead made the characters flat with hardly any personality. Tal's spirtshadow annoys me too, as does the girls one.

I could not bring myself to finish this book. Tal and Milla are separated. The Stormshepards are annoying but this is in part to how Tal and Milla are treating them. I read this series when I was younger and really remembered liking it but it does not hold up. I’m not going to finish rereading it based on what happens in the other books.

While action packed this book doesn't really develop the characters. The plot felt a little artificial as a whole for this book.
