Denis Egan is dead. He's okay with that. Port Haven, the place where souls go, is actually pretty nice. Sure there are some things about his life and how it ended he can't quite recall, but that's how it's supposed to be. Remembering could prevent Denis from moving on to whatever's next. However, something is standing in his way. His twin brother, Matt, can't let go of him, and as long as the living are holding on to his memory, Denis can't rest in peace. So he returns home to find out why, only to realize that the circumstances surrounding his death are not at all what he imagined. To uncover the truth about what happened, Denis teams up with Matt. But leaving Port Haven for too long has painful consequences for Denis, and Matt's obsession with his brother's passing is driving a wedge between his still-grieving parents. Can the boys solve the mystery without breaking apart the family Denis left behind? -- From the publisher.
