When a mysterious neighborhood boy befriends his young daughter, stay-at-home dad Craig considers him a godsend--until it becomes clear that there's nothing angelic about him at all.
Craig Finnigan is determined to finish his book this summer, but being an aspiring writer while wrangling his seven-year-old daughter is not easy. So when Alice makes fast friends with a neighborhood boy, Levi, Craig is happy she has a distraction from her constant visits to his home office.
But that happiness soon turns to misgivings as Levi's behavior evolves from that of a shy, odd boy into something far more disturbing. Strange noises in the middle of the night and things disappearing from their home could be explained away--maybe it's the water heater, or maybe Craig simply misplaced his flash drive. Craig can't explain his paranoia, but he feels sure Levi is behind it.
As Levi's visits to their backyard become more and more frequent, Craig finds himself the unwilling participant in a game he never asked to play...and one he's not sure he can win.
