 I liked this book better than the first in the series, and you can see how much I loved that one in my review ! These are just so, so good! I was iffy when I picked up LEVIATHAN AND BEHEMOTH at the library, I didn't think they looked that appealing or similar to what I usually read. I'm glad I stepped out of the box and put my trust in Scott Westerfeld's writing and those of you who encouraged me to read them because these are amazing! Just like he did with UGLIES, the LEVIATHAN trilogy is entertaining and action packed until the turn of the last page. 
 This behemoth of a novel, (see what I did there) may be daunting at almost five hundred pages but once you get into it-the first chapter even-you'll be hooked! 
 The plot is a continuation of the Darwinists vs Clankers of LEVIATHAN except now Alek doesn't know which side to fight on. His character really developed a lot in this novel, he grew into himself and his title, taking charge when Count Volger couldn't and really proving himself worthy. 
 Deryn is in a bit of a jam, someone close to Alek found out her secret of being a Mister and blackmails her! She also is constantly at war with herself trying to work out her feelings for a certain prince who is none the wiser of her gender. 
 Many new characters are introduced and I loved them all, they each had such a key part in the story and never seemed unnecessary. Even with minor characters Westerfeld shapes them so well they seem like real people, they each have their own problems and flaws. 
 Like I mentioned in my review of LEVIATHAN, Westerfeld does an magnificent job of creating and describing this vast, original world he created and all the inventions, creatures, and humans that populate it. I loved the illustrations, they really help you picture everything in your mind and are very well done. 
 Crazy ending, too! I can't wait to see what happens in the final novel of the trilogy, GOLIATH. 
 I can go on but you should just read it yourself!
