In 1652, Ireland is known as Wolf Land. Oliver Cromwell's army have arrived. Properties will be seized. Land will be cleared. Wolves will be destroyed. In the small village of Wolf Wood, Cromwell's men face far worse enemies than those in the rest of the country. The wolves here are bigger, stronger, more intelligent. Could these wolves be something different? Could these wolves be forming an army of their own? Sorcha Moore has grown up hearing stories about the unusual wolves of Wolf Wood, but her fears are more immediate. She fears what will happen to her older sister, Peggy. Peggy is to become the latest mistress of Lord Tolbert, so that the Moores can keep their farm. Sorcha is frightened, too, of her own future marriage to Sean, a farmhand. If the decision were hers she would be with Rory Farrrell, a young blacksmith. Peter Moore has never let his daughters have their freedom. If he had, they might have turned out like their mother before them - a woman many thought was a witch. On the night of Bealtaine, Rory Farrell is bitten. Unable to tell Sorcha that he must join the ranks of the werewolves who protect Wolf Wood, he tells her he is moving to Dublin. No matter what his new responsibilities, Rory cannot truly abandon Sorcha. As the years pass, and Sorcha grows from girl to woman, he watches over her night after night. But when Lord Tolbert's eyes turn to Sorcha, will Rory be able to keep her safe?
