Insane, they would say. Delusional. Mental. Leo Valdez has been labeled all those sings ever since people saw him talking to thin air. He says he's talking to ghosts. That he can see the spirits that haunt the earth. But there's one that he meets who's stuck between life and death. Nico di Angelo. Everyone had thought the boy died years ago, but apparently not. He needed help from Leo to either live or die. One wants him to live while the other wants him to die. Read as time runs out for the two boys as they grow one strange relationship with each other that has to do with saving each other multiple times.
