Eighteen-year-old Naomi Carter has always lived in her protective bubble - raised in a tight church community, sheltered by her grandmother, and taught to stay away from "trouble." Trouble walks in anyway when she takes a part-time job at a boxing gym to help pay for college.That's where she meets Kade Rivers, a 23-year-old tattooed boxing coach/fighter with a reputation for being reckless both inside and outside the ring. He's the type of man Naomi's been warned about all her life: dangerous, white, covered in ink, and always carrying shadows behind his smirk.But Kade notices the quiet girl with honey-brown skin and big, curious eyes who flinches at the sound of a punching bag. He teases her at first, then slowly protects her, then - against both of their wills - begins to fall for her.Naomi, drawn to his bruised knuckles and broken smile, must decide: is he the sin that could ruin her life, or the freedom she's been secretly aching for?
