A cold-blooded m******e left him with nothing but a promise and a ghost. Kael, the last true Alpha of a fallen bloodline, watched his mate die and his pack perish in a brutal act of betrayal. He was left with a single, devastating vow: to protect the son he couldn't raise and exact a vengeance that would burn the world to ashes. For three years, he lived in the shadows, a man reborn as an agent of fury, mastering forbidden magic that came at a terrible price. Now, he's returned, not as a wolf, but as Elias Thorne, a business tycoon with a hidden fortress and a secret army. His life is a meticulous blueprint for war, with one singular purpose: to prepare a world for his son's destined return. But his plans are threatened by a woman who is as fiery and unpredictable as he is ruthless. As their paths cross in a web of power and passion, Kael finds himself torn between his mission for vengeance and a dangerous desire that could shatter his carefully constructed world. Will his consuming rage lead him to victory, or will the darkness he embraces finally claim the last true Alpha?
