Leviathan + Behemoth + Goliath = One awesome book series.
Set in an alternative Europe at the start of World War I, it features two very different sides; Clankers, who are masters of the machine, and Darwinists, who can manipulate DNA to craft special creatures.
Darwinist Deryn (a.k.a. Dylan) Sharp has always wanted to fly, and she's not going to let anything get in the way of that- not even the fact that they don't let girls into the British Air Service.
Clanker Prince Aleksander of the Austro-Hungarian Empire is on the run. His parents have just been murdered by his granduncle, and now he has a new target- Alek.
But after an unfortunate attack on the ship Deryn is stationed on, the Leviathan, it seems that Alek and his men are the only ones who can save them, in return for being saved themselves. Can this alliance work out on both ends?
This series is amazing. I'm having a hard time returning it to the library, it's that good. Because of some complex schemes, I recommend this book for ages 13 and up. Author: Scott Westerfeld. Release date: 2009 On a scale of 1 being not so good, and 10 being the very best book I've ever read, I rate this series an 8. Check out the website at http://scottwesterfeld.com/books/leviathan/
