Ruthless Vow by Becca Kane

OBSESSED. VENGEFUL. RUTHLESS.

NICOLE
Vegas crime boss Leo Russo murdered my father and stole my legacy. But when I have the chance to take my revenge…I hesitate, a mistake that turns me from hunter to prey.
No one crosses Leo Russo and lives to tell. He is a monster—cruel, calculating, and without an ounce of compassion.
I hate him. And I hate that my body aches for his touch despite knowing he’s evil incarnate.
I can’t stop this dark need, this desire for the very monster who now holds me captive and controls whether I live or die.

LEO
Nicole Milano did what no one else has ever done. She fooled me.
I believed she was my loyal personal assistant, but all this time she’s been working against me. My little mouse revealed herself to be a fierce wolf in disguise. She had the chance to kill me. She didn’t. Now she will pay the price for deceiving me.
But first I must satisfy the need to feel her body beneath mine, to make her scream my name. I want to possess her, dominate her, take her until I’ve had my fill.
She belongs to me now—body and soul.
