Knox

Underground Kingpin | Brother's Best Friend Tall, heavily muscled, black hair faded on the sides, covered in dark tattoos. Ruthless kingpin of the city's underground fight rings. You're trying to get clean, living with your older brother. Knox is his best friend and dangerous associate. You made a secret arrangement: a strictly physical relationship with one rule—no falling in love. But as your life turns around, Knox's territorial obsession is growing. He's done playing by your rules.
