On Noah's hometown of Martha's Vineyard, the summer of 1997 unfolds with the promise of a carefree vacation for a group of ambitious teens: Sammy, Eugene, and Ben. The story centers on a young, hungry journalist-in-training who is eager to document the world around him, turning a hush-filled island into a playground for discovery. Abby, Noah's widowed mother, runs a cozy bed-and-breakfast that offers a steady anchor in the midst of the sea-salted routine and small-town chatter. The dynamic between a hopeful kid with a notebook and a mother who keeps the home fires burning sets the emotional tone for what’s to come.
But the peace of this coastal enclave is shattered when local children vanish, only to reappear the next day in a quiet, almost lifeless trance. The unnerving pattern turns fear into a kind of creeping rumor, until a terrifying incident leaves Ben spiritless after an ocean assault, witnessed by a young bystander who whispers of a cackling witch pulling him beneath the waves. The mystery pulls Noah deeper into the mystery, a choice that tests his limits and threatens his friendships as he refuses to let the disappearances go unanswered.
The investigation pushes into darker corners of the island when a prime suspect emerges: Miss Halverson, an enigmatic elderly woman dressed in black who recently moved into Noah’s mother’s boarding house. With local authorities and even the town editor skeptical or slow to act, Noah turns to a seasoned skeptic for help: Gene Carruthers, a gruff, retired police detective whose own life was ripped apart years earlier by the kidnapping of his son. At first, Gene Carruthers clings to a belief in “real monsters” and dismisses Noah’s fairy-tale notions, yet the stubborn stubbornness begins to crack as the boy’s persistence echoes through the fog-draped landscape.
As the two allies press the case, they navigate through the island’s damp woods and shadowed trails, slowly confronting a truth that is far more supernatural than they anticipated. The clues grow stranger and more chilling: a stash of missing children’s shoes, traces of a ritual-driven appetite for youth and life force, and a mounting sense that the threat is ancient and cunning. The pair eventually uncovers the witch’s lair, a revealing and harrowing space that binds the disappearances to a dark, age-old pull on the town’s youngest residents.
With Sammy and others drawn into the vortex of danger, Noah and Gene Carruthers rally the group for a climactic confrontation against the creeping evil. The battle is equal parts wits and nerve, as they outsmart the witch, breaking her spell and shattering the grip she holds on the children. One by one, the affected kids restore to their former selves, the town begins to breathe again, and the community begins to recover from the nightmare that had gripped its summer hush. In the end, the ingenuity of a determined boy, the guarded resolve of a weary detective, and the invisible threads of friendship prove strong enough to save the island from an ancient hunger that fed on youth and fear.
