Five years ago, a desperate night at the anonymous Eclipse Masquerade Club left human Aria Lane pregnant by a breathtaking, commanding stranger whose face she never saw. Five years later, she is a fiercely protective single mother raising twins who possess a terrifying, unexplained strength. Desperate for money to protect them, Aria takes a job as the executive assistant to the city’s most ruthless tycoon: Xavier "Xavi" Vance. Xavi Vance is a billionaire by day, but secretly the ruthless Intersex Alpha King of the nation's most powerful Lycan pack. Xavi has always viewed emotions as a fatal weakness. But the moment Aria walks into her boardroom, the primal fated mate bond slams into them both. Aria instantly detests the arrogant, micromanaging billionaire who tries to control her every move. Xavi is maddened by a human mate who openly defies her. For a year and a half, they fight an agonizing, breathless corporate war of attraction. Aria keeps her personal life fiercely locked away. Xavi has no idea her mate is a mother. Until the twins turn seven. When the kids' supernatural Lycan nature violently breaks through, Xavi accidentally catches their scent—the unmistakable, dominant lineage of her own blood. The realization hits like a lightning bolt: Aria didn't just hide herself... she hid the Alpha King's heirs.
