Avasarala is finally here!!!

Unlike Leviathan Wakes, I’m venturing into uncharted territory within the series for the first time here. By that, I meant that I haven’t watched any part of Caliban’s War, the second book in The Expanse series by James S. A. Corey duo, in the television series adaptation except for some episodes consisting of Avasarala and Bobbie. Caliban’s War is a superior book compared to Leviathan Wakes in every aspect. This is caused mostly by Corey’s decision to expa

Things go very wrong in the colony on Ganymede.

”It grabbed an UN Marine in its huge hands and tore him in half like paper. Titanium-and-ceramic armor ripped as easily as the flesh inside, spilling broken bits of technology and wet human viscera indiscriminately onto the ice. The remaining five soldiers ran even harder, but the monster chasing them barely slowed as it killed.

‘Shoot it shoot it shoot it,’ Bobbie yelled, and opened fire.

I´ve recently finished the eighth part and I must say that the immense coherency, precision in plotting, and meta context are so finetuned that it is a joy to read. The effort to polish this until perfection without hardly any logic holes, lengths, and errors and to stay comprehensible must be immense and I must say that I´ve rarely ever seen something like that in Sci-Fi because it´s such a difficult task.

Mostly, the novels of a series are closed in itself and there are not so many retrospects

One big thing that stands out to me going back to this after reading all the available books in the series is that my complaint about distinct bad guys not getting introduced until very late in the stories was addressed. From this point on we almost always have a face of the threat through most of the action, and that’s an improvement that made a great series even better.

I also wanted to check this out again after seeing the second season of the TV series. The show has g
OK, I liked this book but...


I think that at its core, this second book is was too much similar to the first one.

I mean, there is a search for a girl (different age but the same basic idea), a mystery about a threat, and the tensions between the policital powers.

The only difference is that while the first book, Leviathan Wakes can be read a stand-alone book if you wish, maybe since the authors weren't sure to get the chance of... expanding it (pun intended)...

The Expanse - 2: The Expanse universe is further expanded with action on Ganymede, Io, Luna, and Earth! Venus looks like it's being alien-formed as the Solar System watches. Whilst the alien intent is self evident, mankind is intent in making the most out of the instability as the forces that started this all off, look to further their aims and goals with the alien Protomolecule. The quest for a five-year old emerges as the central cause that brings Holden, Naomi, Alex and Amos back into the spo ...more

Leviathan Wakes was one of my great reads this year (review: ). It broke into my reading blahs and set off a trend of great reads. After finishing, I promptly placed a library request for Caliban’s War, out of general interest and just the tiniest bit of series OCD. When it arrived, I was in the middle of monthly reads for my book club, then all hell broke open over at Goodreads, resulting in a loss of reading mojo, quickly followed by reviewing mojo.

I was a little hesitant to pick up Caliban’s War because the first book (Leviathan Wakes) was so amazing, how could the second book possibly compare? I was even worried I’d get bored because I thought I’d figured out which characters we’d be following and what direction the story was headed… Boy was I wrong! And happy to be so. It was definitely different from the first novel, and didn’t lack any of the adventure and excitement!

When I read the first book of The Expanse series, Leviathan Wakes I was not that impressed with it. It was, however, an instant hit with the majority of the sci-fi readership. My main problem was that I did not really care for the main characters. Consequently, I decided not to continue with the series. Then a few months ago Syfy started broadcasting The Expanse Season 1 their adaptation of Leviathan Wakes to practically universal acclaim. I wondered if I may have somehow misjudged the book s ...more

I often struggle with sequels, because, in my personal experience, they rarely live up to the perfection of first novels. Therefore, I'm happy to pronounce that Caliban's War was a solid sequel to Leviathan Wakes. I would even go so far as to suggest that it might even be a better novel than the first in some ways.

This novel provides a lot of character development to the cast of misfits introduced in the first book, along with introd
Re-Read 7/7/18

It's so great doing a re-read. I mean, I was somewhat hesitant at first but it's so rich with detail and the action is perfect. And by action, I don't just mean Bobby in her Goliath suit. I mean Avasarala on her com. :) Avasarala is a FORCE to behold. :)

All in all, though, this second book happens to kick major butt. Venus really stole the show by the end, but all the Powers butting heads was also fun as hell.

Did anyone else whoop when Avasarala and Bobby got on the Rocinante?

"...“That man’s asshole must be tight enough right now to bend space.”..."

It must be the right time for me and Sci-Fi, because I loved it! Caliban's War is the second installment in the "Expance" series and I actually enjoyed it better than the first one! No, nothing was wrong with the first one either, I even missed our pulp-noir drunken detective with nothing to lose, but fortunately the authors gave us to kick-ass female characters who more than made up for Miller's loss.

The Space Opera continues and it ain't over until the fat lady sings . . . or, until you make your way through several oversized tomes!

I don't really have anything to add to this review that I didn't already already cover in my review of Leviathan Wakes. It is another epic in the middle of a bigger epic. The characters are dynamic and interesting. The action is intense. The horror is terrifyingly. All in all, a satisfying and exhausting experience.

In this second installment, we're still following events I already know (more or less) from the show.

After billions of years of being in the Solar system, unable to do what it came here to do, the protomolecule is working hard on finishing its job now, whatever that job is.
We meet a few new players in this second installment, most notably Avasarala and Bobbie. The former is a potty-mouthed deputy to the UN Secretary General, the latter a kick-ass Martian Marine.

Dying without any answers seemed terribly cruel.

I read Leviathan Wakes way back. While I enjoyed it well enough, I wasn’t compelled to rush off and start the next book immediately.

But, here we are. And given that this has now been adapted into a TV series (which I haven’t watched yet), the time has come to pick up where I left off…

Caliban's War (Expanse, #2), James S.A. Corey

Caliban's War is a 2012 science fiction novel by James S. A. Corey (pen name of Daniel Abraham and Ty Franck). It is about a conflict in the solar system that involves Earth, Mars, and the Asteroid Belt (colonies of people living on asteroids, referred to as "Belters"). It is the second book in The Expanse series.

On Ganymede, Mei Meng is kidnapped from her preschool by her doctor. Several hours later, Earth and Martian space marines are attacked and e

Yup, I drank the damn Kool-Aid and now I’m reading this series of inconveniently huge paperbacks. Sigh. What can I tell you: “The Expanse” is everything I could possibly want a space opera to be, both on the page and on the screen. It’s intricately plotted, furiously paced (I have screamed: “One more episode!” at my husband too many times to keep count), filled with awesome and diverse characters, and the world building is amazing. Now my struggle is figuring out how to fr
CALIBAN'S WAR is the second book in The Expanse series, and this is the one that made me a true fan and ensured my continuation of the series.

I want to make a special mention of the character Chrisjen Avasarala, the UN official-OMG her foul mouth had me laughing my ass off! She was a new character in this volume, as was Bobbi, (a Martian Marine), and Prax, a botanist on Ganymede. I loved them.

I also want to say that this narrator is fabulous!

The second novel in The Expanse series finds Holden and the crew of the Rocinante trying to stop further attempts to weaponize the protomolecule, with a little help from a Martian marine, a belt-born botanist, and a UN power broker.
As exciting and action packed as the first book, and nearly as good. The ending, while spectacular, doesn't quite pack the emotional punch of its predecessor.

I am buddy reading this series with my boyfriend – which is something we have not done before but which is enhancing my enjoyment of this series immensely. But that meant that I had to take about a month’ break in the middle of the book so that he could catch up – and then he sped up and finished the book around 200 pages before me (which is just rude).

This book starts some time after the events of the first book – and the structure mirrors that one a bit too closely I found. In the prologue we

Way back in 2012 I listened to the audiobook of Leviathan Wakes, and loved it. It was awesome. And then I picked up a nasty case of "Series Blah" which left me in this emotional hinterland between wanting to continue the series because I really loved the first book, and dreading to read it because either it wouldn't live up to my expectations, or it would be so awesome that I would need more and there was no more to be had, at the time.

Now I have read it... and I was kinda right on all counts.

“Well, you’ve got a full load of torpedoes and bullets, three Martian warships trailing you, one angry old lady in tea withdrawal, and a Martian Marine who could probably kill you with your own teeth. What do you do?”

Always a bit worried with second volumes but Caliban's War is another amazing adventure, very cinematographic, which explains why the tv series is so popular. The plot carries on from the events of Leviathan Wakes and once again Holden i

I enjoyed this even more than the first time around. Bobbie and Avasarala are such great characters, and watching the way the Rocinante team comes together is a treat.

I'm finding it interesting to reread these after watching Seasons 1-5 of The Expanse show, and seeing the choices that are made not just with respect to storyline, but also how certain characters develop. I wouldn't say one is better than the other, they are just quite different. What they have in common is tha

It's a pretty safe bet that those who liked the first Expanse book, will enjoy Caliban's War , too. I would add that new readers should start the journey with Leviathan Wakes , and not here, as this is not one of those loosely connected, self-contained, ongoing francizes like The Dresden Files or Vorkosigan Saga. The story picks up a few months after the cataclysmic events described in the debut novel, and will spoil said events for the less cautious reader. My review also may contain spoilers ...more
