I Bought a Mafia King. He Met His Match.

Five million dollars buys Joan Vance a stranger's freedom—and an ally she never saw coming. Betrayed by her partner, the woman secretly holding power on Wall Street bids for Jonathan Moretti at an underground auction. She has no idea he is a feared mafia boss. He has no idea how much power she commands. As blackmail, betrayal, and revenge pull them into each other's lives, every test of loyalty brings another secret into the open. What begins with a winning bid becomes an alliance between two people their enemies should never have underestimated.
