When an illegal underground fight leaves my brother in the hospital, I make a desperate deal to save his life: I volunteer to fight in his place. In thirty days, I've got to walk into the ring, a woman in a man's world—and I've never even thrown a punch. I have one chance to survive. I need a badass who can teach me to be as tough as him. I need Aedan O'Harra, the blue-eyed, Irish beast of a man who everyone fears.

But training together means getting close. Every touch of his hands makes it harder to control my feelings. I begin to see the man inside him, the one no one else can. Can I help him break free of the dark secrets that haunt him and can we save each other, or will we both be defeated?
