Taken Boy by Loki Renard

Revenge has no happily ever after.

Bobby Cornoli has the New York underworld in chaos. A brutal twenty-two year old gangster prodigy with a vendetta against a heir to billions, he’s about to wipe his biggest enemy off the map. But Bobby’s been making some powerful enemies himself, and he just landed on the radar of a man it’s better not to know.
Angelo Vitali is the real deal, a dyed in the wool Sicilian who knows exactly how to deal with a wannabe mafioso. He’ll take Bobby, break Bobby – and love every minute of it.
