In a world where assassins stand above kings and presidents, one name is feared above all others: Y/N. Forged by abuse, raised by violence, and driven by one promise—to protect his younger sister—Y/N became the Agency’s greatest assassin. Cold. Untouchable. Unreachable. Everything changes when he’s partnered with Adrian Locke, an Enigma Alpha whose strength rivals his own and whose unwavering affection begins to crack the walls Y/N spent a lifetime building. But love comes at a cost. As Y/N slowly learns he may be worthy of being loved, Simone—the sister he sacrificed everything for—must watch the man she secretly loves fall for her brother instead. In a world built on blood, power, and impossible choices, some hearts heal… …while others break quietly enough to become dangerous.
