BZRK: RELOADED by Michael Grant
The second book in the mind-blowing new series from the author of GONE. The first battle is over, but the war rages on. Sanity or madness? Truth or happiness? Love or survival? In the nano, you don't get to decide. Noah and Sadie are now trained twitchers. They know how to wire a person's brain from the inside, and how to get out alive. But they're still reeling from their first encounter with the Armstrong Twins, and there's no time for grief. As long as Bug Man has control of the US President's mind, the future is on a knife-edge. Escapism doesn't get more thrilling than this.
