The stately Willow Hall, which Mr. Montrose built as a summer retreat for his family, is now the only home the Montroses can have.Lydia resents that she's lost everything. But her resentment turns to disquiet when it becomes apparent that Willow Hall hides dark secrets that no one in the Montrose family could have predicted, like the ominous messages Lydia keeps receiving: "You attract them. Prepare."

Summoning powers she barely understands, Lydia must engage the forces around her to keep her family safe, while protecting the blossoming love she has with John--who has secrets of his own.
