Black Swan by London Miller

In the blink of an eye, Karina Ashworth lost everything.
But in the pits of her despair, she finds a new purpose—a reason to keep living.
Uilleam Runehart might have shown her how ruthless he could be, but she’s no longer the girl he once knew.
No longer innocent and blind to the cruelties of the world, she’s now a woman fueled by vengeance and fury. And by the time she finishes with him, an empire will fall.
His actions have consequences, and she would be his reckoning.
