Some desires can’t be buried. Especially when they run in the bloodline. Breeding season has come to Ashfall Hollow. Cealean’s heat arrives earlier and he’s alone with the one alpha he should never want. His grandfather. He should be ashamed of how easily he obeyed every whispered demand, how eagerly he offered himself. But even after the fever breaks, he can’t shake the memory of how safe he felt in Isander’s embrace. These things happen. It doesn’t mean anything. Isander insists it was just instinct, what any elder alpha would do when a young, inexperienced omega needs help—nothing more. But the way his grandson clung to him, moaned his name and begged for more, was more than duty; it was the dangerous spark of a bond he shouldn’t let rage out of control. Breeding season may be over, but neither can forget how right it felt to be together. After Cealean confesses he wants more, Isander makes a promise: when Cealean’s heat returns, Isander will claim him—damn the consequences. The bond has taken root and instinct doesn’t play by the rules. Can they wait? Or will they break beneath the weight of the memories they can’t escape, and a need that won’t fade?
