At nineteen, human Wren Vale was the forbidden obsession of Kael Voss, Alpha of the Iron Fang MC. One night of animal claiming left her pregnant, marked, and broken. When the pack elders discovered she carried a hybrid heir, Kael publicly rejected her and ordered her execution. She escaped with her life and the secret growing inside her. Five years later her son is dying from the incomplete mate bond. The same bond is slowly killing Kael. Desperate, Wren walks back into the den of the man who tried to have her killed, drops to her knees in front of the entire club, and begs. Kael does not forgive. He claims. He locks. He knots. But Wren did not return empty-handed. She brought leverage, enemies, and the truth that without her complete submission Kael’s wolf will tear him apart. What begins as pure punishment becomes an obsession neither of them can survive.
