Kane "Rebel" Sturgess is the newest fighter at The Underground, an illegal cage fighting racket that's bad news...and big money. He's set to make his fortune with the only thing he's ever been good at. Fighting dirty. He's got no job, no family, no ties and this is his ticket to an easier life. Winning a Championship in this place could mean better and more honest things for a guy like him. Enter Charlotte "Charlie" Croft, undercover detective with the Victoria Police, tasked with bringing an end to The Underground. She's got her work cut out for her considering most of her fellow cops are taking bribes on the side from the ringleaders. The only chance she's got is if she heads in undercover and immerses herself in the life. She needs to get close to her targets, collect evidence and pounce...all without being found out. What she doesn't expect is to fall for one of the fighters. A handsome, dangerous, bad boy with a rap sheet longer than War and Peace. A fighter who goes by the name Rebel. There's only one thing he's interested in cracking, and it isn't The Underground. It puts Charlie in an impossible position and she's got to make a choice before she winds up in a body bag. Her heart or her career. She can't have both...or can she?
