Boston's Nightmare

Sierra Borrelli has been running for over a year-ever since the night her husband, Detroit mafia boss Darius Borrelli, nearly beat her to death. When he left town on business with most of his crew, Sierra took her chance. She left her wedding ring on the dresser, dyed her hair, and disappeared with a stolen duffel of cash from one of his cleaner safehouses. No fake death, no explosion-just silence, and a plan to survive.

Now in Boston, Sierra lives fight to fight, stepping into underground rings for cash under the name "Nightmare." Every win means a few more nights of safety, a few more miles between her and the monster she married. But when her latest victory catches the eye of local mafia boss Damon Romano, everything changes.

Damon isn't like Darius. He's powerful but controlled, dangerous but deliberate. When Sierra crosses paths with one of his rivals, Damon steps in-and suddenly, she's under his protection whether she wants it or not.

Sierra doesn't trust men. She especially doesn't trust ones like Damon. But he's patient. Watchful. And he sees right through the walls she's built. The more time she spends in his orbit, the harder it becomes to keep her guard up-and the more dangerous it is if she lets it down.

Because Darius is still out there. Still hunting her. And if Damon gets too close, Sierra knows exactly what will happen:

The people she lets in always end up bleeding.
