A hint from their parents’ past puts Amy and Dan on the trail of secrets their grandmother Grace would NEVER have wanted them to know. Awful memories begin to crowd in on Amy, just as her enemies circle closer. How far would she go to protect Dan? How much of a Cahill is she prepared to be? Perhaps Grace was right – some secrets are better left buried.

This is one of the better book out of the series.
I mean come on! It takes place in Australia~ How can some one NOT enjoy this book? :)
I'm going to give a generic review of the series. Basically because I'm lazy and don't want to write 39 reviews. Okay, 11.

We finally read Book 1. And then because we liked it so well, the entire series. One son (age 12) has read them all, the second son (also age 12) is on Book 2. And son #3 (age 8) will be starting as soon as he finishes his current book.

I thought the premise of this book very interesting. I loved how they integrated history and geography along with problem-solving skills and c
The plot thickens, and the adventures are more and more dangerous. Some intriguing new characters appear. Too many coincidences in this book.
I have an assumption about the Madrigals and I really want to know if I’m right or not.

"There is Rakata."They could see it now, the island with the volcanic peak of Anak Krakatau, the child of Krakatau. Dan felt a chill along his spine.
It must have looked similar to this when Robert Cahill Henderson first arrived. It was flat on top, and the white smoke w
Wow. Wowowowowowowowowow.

What is up with these authors enjoying torturing me?!

Lemme take some deep breaths...I can't believe what Jude Watson did in this one. Seriously. SERIOUSLY?!

I think this one, out of the previous ones, was the best written. It's between this one and the first one by Rick Riordan. Both of them delved into the emotional parts of the narrative as well as giving you a grand picture of just how dangerous this clue hunt really is in the story.

Isabel "Cobra" is evil. EEEEEEEVIIII
I like the 39 Clues “In Too Deep” by Jude Watson because of the new characters they introduce and all the intense situation in each book. This is number six in the series.
Dan and Amy competition is getting bigger and harder to beat.

Dan and Amy are starting to learn more about their parent's past.Since their parents deaths, Dan and Amy are getting clues that they hid prior to dying. Amy and Dan are traveling under false Australian passports. They have to meet ground transport when they land in M
Time for another installment of Picky Bitch Reviews Books For Which She is Not the Target Audience. ;) Although I have to say, I was actually pretty impressed with this one for the most part! It's set mostly in Sydney and I like how the author actually seemed to know the Circular Quay and Rocks areas a bit and wasn't totally making it up. I do have to question their logic in taking the bus to Circular Quay though when there's a perfectly good and MUCH FASTER train :P I've done the bus myself whe ...more
I waited a little bit for this book to come to me - and it was worth the wait.

I love how we end up in sunny Australia. I also like the addition to Dan and Amy's family, with another cousin (Shep) to help them find the 39 clues. I understand that they want to keep him out of danger, so they make up a few stories to throw him off track.

You also find out a bit more of Nellie's skills as an au pair. At the moment, I'm a bit worried as her as an au pair. She seems to be... too perfect in the 39 clu
I am still enjoying this series of books - although I do find it hard to remember all that's taken place in previous stories since the books seem to come out about every two months or so. anyway - it seems like the later books are getting better probably because we're finding out more clues. Here, Amy and Dan are in Australia, and they meet more Cahills, learn more about their parents, are almost killed (a number of times, of course), and find out some interesting things about Nellie. In the pre ...more
A terrific book, one of the best in the series. So many new layers to the tale were revealed and new questions asked to spur the story on. The educational stuff was woven into the story much better than in some previous books, with no sense of being lectured this time. There was some really fascinating stuff, like underground cities and wild Australian snack foods. The Clues mystery, the various Cahills, who to trust or distrust, their past and their parents all wove together into an exciting an ...more

I feel cheated. Utterly cheated. This has got to be the worst 39 Clues book I've read. Throughout the book, I was bored, which I suppose is entirely subjective, but aren't all reviews? I mean, all of our reviews/opinions are subjective; they're influenced by our own opinions on certain topics (i.e. when you complain about slut-shaming in a novel, your personal beliefs are butting in because you don't believe in slut-shaming.) But I digress.
But seriously, I just feel so cheated and disappointed,

the book that i took about a fourteen years old Amy Cahill and her younger brother, Dan, hear to the Land down Under to discover what their own mother and father knew about the humt for the 39 Clues.

I am disgusted by the amount of incestuous thoughts of the characters. It should be a family tree, not a shrub.

I love when a fiction makes me seek the factual portions. Coober Pedy is real and the pictures are interesting. There are other underground town around the globe.

FACT: (copied from wikipedia) Coober Pedy is a town in northern South Australia, 846 kilometres north of Adelaide on the Stuart Highway. According to the 2011 census, its population was 1,695 (953 males, 742 females, including

This book is thrilling adding a new opponent to the clue hunt and making harder than ever to find the clues and Amy and Dan find about a thrilling truth about their family. They have to go through many challenge to find the clue which is something so easy they could've guessed because it's so common.
I did a book report on "In Too Deep" and I got a good mark, maybe you could use it to help your learning.

Part 1 (Character Paragraphs):
Amy Cahill:
Amy Hope Cahill is a Madrigal (from the Cahill family) who is the daughter of Hope Cahill, a Madrigal and Arthur Trent, a former Vesper and an honorary Madrigal. She was born in 1994 in Boston, USA.

one of my favourites of the series seems to be this one(6) vipers nest(7) and storm warning (9) that I always re-read. Really
like this book. I read this series in grade 2 and I remember thinking(in my 7 yr old mind) "eleven is not to young to do this stuff" and since then I have read a few of the books when I was 11 and I was like "I would die attempting this stuff this is crazy!" Same when I was 12. Amy is most like me, but Dan is hilarious and he's closer to my age and he wears converse! The

I am at the part where Amy and Dan start to think that there Au Paur Nellie might just be somone that is against them! I like the book and it gets better!
The 39 Clues: In Too Deep is a fictional book in which Dan and Amy Cahill, the main characters of the series, travel to Australia to find the next clue on the quest for the 39 clues. When the siblings go to Java from Australia, they stay in a cave for the night. In the middle of the night, they realize that it is on fire and flee. While helping them to flee, their hidden ally, who they think of as their enemy, is unable to escape. This book is great for anyone who loves mysteries and books that ...more
good book you really should read this series!!!
Still interesting, but this is the longest. series. ever! I want to find out how it ends, so I'm pushing through. Apparently 4 books to go. Fortunately they are only a couple hundred pages each, so they should go quickly. I am enjoying that the characters are traveling around the world to many places I'll never go, so it's been really neat to learn some history here and there (though I think the true history is starting to become less and less and the "history" shared in the book is becoming mor ...more
Unlike the first five books in which the hunt felt like a fast-paced game to beat the competition in finding the 39 clues, Book 6 focuses on family and ends in a more serious tone. Things turn deadly, and fourteen year-old Amy begins to have flashbacks of the night her parents were killed in a house fire. Just like its title, this one pulls you in deep as we get closer to the finish line.

Amy and her eleven year-old brother Dan Cahill are in Australia this time, following their parents’ footsteps

While good, this was an interesting departure from the plotlines we've come to expect from the series. With no definite clue to trace, Amy and Dan head to Australia on a whim. There they meet up with their father's best friend. Shep is a bush pilot who seems to know everyone and everything, and is more than willing to house Amy, Dan, and Nellie for a few days. Soon enough though, the Kabras, Holts, and Irina are hot on Amy and Dan's trail.

So here, in this book, we will find out how Amy and Dan's parents died. Were they murdered? Did their Mom really went in JUST for their Dad? Visions kept on flashing on Amy's mind and she's not telling her brother. It all started when Ian called her to meet for her to know what really happened to her parents. And when she g ...more

Review posted originally at Bibliophilia, Please

In Too Deep is the sixth installment of The 39 Clues series and is written by Jude Watson, who also wrote the fourth book - Beyond the Grave. It begins with Dan and Amy Cahill after they wrap up their business in Russia in The Black Circle. The children travel to Australia, being as it is the last trip they knew their parents to take. Along with their au pair, Nellie Gomez, and Saladin the cat, they go Down Under to meet their father's cousin, Shep

But along the way, Amy uncovers terrible memories about her past that she can't share, and even keeps them from Dan. The pair of siblings get confused during their search, memories coming back to them, being chased by their competitors, unsure of who to trust and who not to trust. Their confusion leads to mistakes, and they work hard ...more

This is my first time reading any book in the 39 Clues series, and yet in reading book 6 I found myself understanding the main story line. This was a great read in my opinion as Amy and Dan found out what happened to their parents and who did it as they continued to look for the 39 clues in Australia. They'll find the some of the world's poisonous snakes and spiders are half their worries.

Through the course of the book they learn that someone who they thought couldn't be trusted, in the end was
4.5 stars. I think this author has done the best job of any of the authors writing books for the ten-part 39 Clues series. This book was awesome, and looking back at my reviews of the previous installments, I apparently thought Jude Watson's last book for this series was one of the best as well. I'd never heard of this author before, but the writing and pacing were solid and exciting; very well done.

In this book, Amy and Dan, still on a race around the world to find the "39 clues" that will make

I was extremely impressed by this series. I started listening to the Maze of Bones audiobook while at work. I enjoy listening to young adult series as they aren't too difficult to follow while also concentrating on my computer. After listening to the Percy Jackson series 2 or 3 times I figured I'd give this Riordan book a try. I was pleasantly surprised to find a compelling mystery! The Cahill kids are likable protagonists on a bigger adventure then they could ever have imagined having in their ...more

Following the stamps on their parents’ passports they found in Russia, Amy, Dan and Nellie make their way to Australia in hope of finding a long lost cousin. The cousin is fortunately on their Dad’s said rather than their mother’s treacherous Cahill relatives. They need to find the path their parents had taken in order to find the next clue and only their cousin knows the path they took. But when Isabelle Kambra makes a threatening appearance and enter
