"In the wake of a scandal, the Montrose family and their three daughters -- Catherine, Lydia and Emeline -- flee Boston for their new country home, Willow Hall. The estate seems sleepy and idyllic, but a subtle menace creeps into the atmosphere. Remnants of a dark history that call to Lydia, and to the youngest, Emeline. All three daughters will be irrevocably changed by what follows, but none more than Lydia, who must draw on a power she never knew she possessed if she wants to protect those she loves." --
