Kirstin has never been out of her den before, but now one of her pack is seriously injured-he may even be dying. Desperate to help, she races straight to Middle March, the borderland between Scotland and England, and falls right into a dangerous trap. As the new laird of his clan, Donal MacFalon has made it clear that he, unlike his brother before him, will honor the wolf pact, an agreement their father made with England's King Henry VII to protect Scotland's wolf shifters, the wulvers, who most believe to be only the stuff of legend. Wulvers, though, are very real. Kirstin knows. She's one of them. When Donal MacFalon turns those steel blue-grey eyes her way, she realizes she's facing something far more dangerous in this man than any trap. This man, already promised to another, has a power over her no man or wulver has ever had before. When he opens his castle and his heart to her, she finds herself willing to risk not only her own heart, but everything she's ever known, just to be with him. Kirstin will find herself caught--between the man she loves and his intended bride, between her pack and a human world frightened of her kind, between nations whose hatred runs deep. Kirstin will be forced to make choices no woman, or wulver, should ever have to make. All for one man, whose love goes beyond borders, nations, or legends, whose heart beats only for her.
