The Troubled.

Jehryd doesn't know what's happening when he wakes up in a white room with no memory. But what's outside the room is even more confusing. Horrors behind every corner, mysteries behind every door, he believes he will die. Until he finds people like him who were kidnapped, their memories erased, and thrown into this nightmare. The hallways, he finds out, are a part of a game called the End Battles. The goal is to shut down the system or die trying, though only five can make it to Stage 2. When he joins the team of ten people he expects to win, he has to. It's either that or die. So when he meets Bliss, the girl of his dreams (literally) he wants to help her win too. But can he really beat the system or die trying like his predecessors? And does he really want to help a girl who he hardly knows? He also feels as if she's keeping a secret, but does he really want to find out what it is?
The troubled mind of his isn't so sure.
