His to Keep by Leo Rivers

The mafia are my sworn enemies.
But then I save a kingpin’s life.
As an ER doctor, I save the lives the mafia throws away.

But one night I get involved against my will. Caught up in the crossfire of a mafia shootout, I do the unthinkable — I save a mafia boss’s life.
And the Thorne family always pays their debts…
Now Thorne lieutenant Colt wants to repay me for saving his boss’s life. I don’t want anything to do with the mafia, but Colt is relentless. Money, power — whatever I want, it’s mine.
He won’t take no for an answer. And the more I resist, the more Colt is hell-bent on spoiling me.
Colt is dangerous. But the way he looks at me ignites something in me that I can’t deny.
Whatever I want, he’ll give it to me.

All I have to do is ask for it.
