 Black Heart (Echoes from the Underworld #1) - Blurb

My name is Nicolai Valsetti, people call me Black Heart.

My father has been murdered making me the next king of New Jersey. I was taught to live by three mottos...pride, power, and protection.

With my father dead, and my brother kidnapped, all I feel is pain, all I want is possession. 

I will get my revenge.

The daughter of my rival and biggest enemy has literally fallen into my lap. She was never meant to be part of the plan, but Sophia Kastrati turns out to be the perfect pawn in a very dangerous game of vengeance.

The only problem is, she is as beautiful as she is brave, and has captured my full attention. What started as a war out for blood may very well end in one fighting for her heart.
