Tidepool

In 1913, Henry Hamilton disappears while on a business trip, and his sister, Sorrow, won't rest until she finds him. Defying her father's orders to remain at home, she travels to Tidepool, the last place Henry visited. Residents of the small, shabby oceanside town can't quite meet Sorrow's eyes when she questions them about Henry. When corpses wash up on shore looking as if they've been torn apart by something not quite human, Sorrow is ready to return to Baltimore and let her father send in the professional detectives. Then, she meets Mrs. Ada Oliver, a widow whose black silk dresses and elegant manners set her apart from other Tidepool residents. After a terrifying encounter involving Mrs. Oliver, Sorrow discovers Tidepool's dark, deadly secret, and the town's denizens-human and otherwise-are hell bent on making sure she never leaves.
