Killian Black, the powerful Alpha and King of the United Kingdoms of Ash and Iron, is bound by the Unbreakable Pact: a sacred oath that forbids him from mating until a dangerous celestial event passes, lest he unleash a magical plague upon his people.When his true mate, Harlow Winter, is revealed during the annual Unveiling ceremony, Killian must make an agonizing choice: accept the bond and doom his kingdoms to immediate war, or publicly shatter her heart and command his wolf to forget her. He chooses duty, delivering a devastating, cold rejection that sends Harlow fleeing into the human world with nothing but her life and her nascent, dangerous Forbidden Weaver Magic.Unbeknownst to Killian, his sacrifice was made in vain. Harlow soon discovers that the rejection triggered a rare complication: she is pregnant with three magical heirs—the Triplets of Prophecy—whose existence alone threatens to dismantle the fragile political truce and expose them all to the ruthless Alpha Zarkon, a rival king who orchestrated the curse and seeks to claim the Triplets for his own power.The Chase: Over the next year, Killian is tormented by his choice, secretly using the vast resources of his kingdom to track and protect Harlow from afar, unable to approach her due to his own command. Harlow, meanwhile, is forced to grow powerful, relying on her unstable magic and her fierce maternal instinct to survive, transforming from a low-status wolf into a self-reliant, powerful sorceress.The two are finally forced back together when Zarkon's forces strike, driving Harlow and the three children to the borders of Killian's kingdom for sanctuary. Now, the King who rejected her must convince the woman who hates him to become his political ally and co-ruler—not his mate—as they race to uncover the truth of the prophecy and save the children who hold the keys to the kingdom's past and future. The tension is palpable, the desire is forbidden, and the fate of the five kingdoms rests on whether a broken bond can be healed by political necessity.
