Contract lawyer Sera Voss signs a merger for billionaire CEO Dominic Kane and discovers a hidden clause has made her a member of his werewolf pack. Within hours of signing, Lucian Thorne, Alpha of a rival biker pack, sends men to take her and claims she is his fated mate too. Her signature alone can validate or void the treaty between their packs. With a traitor inside the Kane pack and a hidden enemy closing in, Sera must expose her mother's murderer and rewrite the treaty on her own terms.
