Bleak Harbor — Bryan Gruley

Their son is gone. Deep down, they think they're to blame.

Summertime in Bleak Harbor means tourists, overpriced restaurants, and the Dragonfly Festival. One day before the much-awaited and equally chaotic celebration, Danny Peters, the youngest member of the family that founded the town five generations ago, disappears.

When Danny's mother, Carey, and stepfather, Pete, receive a photo of their brilliant, autistic, and socially withdrawn son tied to a chair, they fear the worst. But there's also more to the story. Someone is sending them ominous texts and emails filled with information no one else should have. Could the secrets they've kept hidden -- even from one another -- have led to Danny's abduction?

As pressure from the kidnapper mounts, Carey and Pete must face their own ugly mistakes to find their son before he's taken from them forever.
