BZRK ~ Michael Grant

After a gore-tastic beginning, this book jumps straight into the action. Noah and Sadie are swept into a secret organization named BZRK that uses miniscule biological robots called biots to do battle with the evil Armstrong Fancy Gifts Corporation, who uses mechanical nanites to rewire government leaders' brains!

I enjoy Michael Grant's books, this one included. They are very action driven and it was extremely hard for me to put one down once I started it. He also wrote the Gone series and has a new one for that coming out in April!
