Efrem is older and a deadly criminal—everything my parents despise—but he's all I want.

I gave up everything to be with him. My parents are strangers to me now. But if that was the price of dating Efrem. I would gladly pay it.

Efrem said he loves me, that he would do anything for me. But he betrayed me. And his betrayal cost me dearly.

In an instant, I see New York's dark underbelly for the ugly hell it is. However I'm determined to make things right, to protect the people I love and reform the bonds I so carelessly broke.

But everything's different now. I can no longer trust the people closest to me. And nothing is as it seems.

Am I too late to redeem my terrible mistakes? And now that I know the stakes, what will my vow of sin truly cost me?
