Hunter Keating is putting his life back together. Sobriety, check. New place to stay, check. Living with his best friend's smoking hot kid sister... that might be a problem. No. It can't be a problem. Hunter owes his friend too much. He's not thinking about Emma as anything more than a completely platonic roommate. Yes, his thoughts of the feisty college student's stare are completely platonic. Same for her laugh. Her stare. Her coffee-inspired groan. Kissing her is out of the question. Falling for her is totally out of line. But some rules are made to be broken...Breaking the Rules is a smoking hot brother's best friend romance packed with heat, humor, and heart.
