"We need you to solve a murder, Six. Your own."

Agent Six of Hearts, teenage super-spy, has been dead for four years. When he's suddenly awakened by a machine that shouldn't exist, he discovers that the city he spent his life protecting has become a terrifying place.

Secret police are everywhere. Thousands of innocent people have been buried alive. And a serial killer is executing Six's friends, one by one.

Six has to search this brutal new world for whoever killed him, before it happens again. But the City is full of people who want him gone...and he's not the only one who won't stay dead.
