Roen Tan is stuck at a dead-end job and life that he won't stop complaining about. Then he gets inhabited by an alien life form and thrown into the middle of a secret war. The Quasing are divided into two factions: the Genjix who believe that humans can only advance through conflict and the Prophus who believe that humans will advance if allowed to live peacefully. Currently the Genjix are winning the war and they want Tao, the Quasing that currently inhabits Roen Tan.
A while ago I was introduced to this world through Rise of Io (see Blogger's Bookshelf for review) and I swore I was going to read more of Wesley Chu's books. I was not disappointed! Admittedly, knowing some of the things that were going to happen further down the timeline kept me from getting fully engaged in some aspects of the story, but I still had a great time.
I've read one or two other reviews that describe this as book to read to get yourself motivated and I have to agree. Reading about Roen's progress in his secret agent training and Tao's demands for better performance from his human host had me looking at my own gut and thinking "I can do better" and start looking at ways to get into shape. If you're in the mood for a book that can inspire you to do more for your diet and exercise, I highly recommend this book.
This was such a fun, action packed, humor filled read. The characters, even the nearly immortal aliens, are so relatable and interesting. It really helped to fill in some of the gaps in my understanding of the world from picking up a later book. Even the villains are entertaining. I love intelligent villains and Genjix know what they're doing. This is a true underdog story and I really want to continue with the series.
If you're at all interested in books about aliens being the driving force behind human evolution, or even just stories about an underdog turning his life around, I highly recommend this book, possibly this series. 4 hoots!
