Twelve-year-old Zach is convinced he'll never be happy without his best friend Jeremy by his side. But both of their lives changed with a bang five months ago, and as far as Zach's concerned, it's his fault Jeremy will never see his twelfth birthday.

When Zach moves with his family to a Chicago suburb, he quickly becomes friends with a group of thrill-seeking kids trying to find a disappearing haunted house. But Zach's not worried. He doesn't believe in ghosts, so he follows them into a wild, dangerous encounter that becomes a battle to decide what's real and what's not.
