Seduce the Alpha King—that was my mission. As a half-breed spy, infiltrating Alpha Kael Draven's world meant stealing the secrets that could save my brother's life. The deadliest shifter alive should have been manageable. His raw intensity, his brutal magnetism... I thought I could resist him. One touch ignited what neither of us could control—a mate bond that consumed everything in its path. Now I'm caught between my sworn promise to protect my brother and the Alpha whose very essence calls to mine. The stakes multiply when hidden betrayals emerge and an ancient enemy awakens in the frozen north, wielding terrifying human technology and determined to obliterate our world. They see our bond as a vulnerability. They don't realize they've made their fatal mistake. What they perceive as weakness is about to become our greatest weapon.
