To save her dying pack, twenty-two-year-old Elara Veyne agrees to marry Kael Draven, the ruthless Alpha of the Northern Territory. She knows the marriage is a sacrifice, and she is willing to give up her freedom to save the people she loves. Then, on her wedding night, she discovers that Kael is not her mate. Her true mate is Lucien Vale, the Alpha of the neighboring Shadow Territory, and Kael's greatest enemy. For years, the two Alphas have been locked in a bloody rivalry, each believing the other responsible for their family's deaths. Now an ancient prophecy claims that whoever possesses Elara will control the entire werewolf kingdom. Suddenly, Elara becomes the prize in a war between two powerful men, but Elara refuses to belong to either of them. When assassins attack her wedding and she begins uncovering the truth behind the prophecy, she discovers something far more terrifying; the prophecy was never about which Alpha would possess her, it was about what would happen when they tried. Because Elara isn't destined to give either Alpha the kingdom, she's destined to destroy them both.
