Unwritten Rules — Alison Henderson

Things aren't going Madelyn Li's way. Her bodyguard agency is teetering on the brink of bankruptcy, her grandmother keeps hatching plots to marry her off, and someone is trying to kill her latest client. All she wants is to safely escort thriller writer and former CIA agent Carter Devlin on his cross country book tour and collect her check, but two obstacles stand in her way: a shadowy assailant and her own growing attraction to her dashing client. Carter Devlin has agreed to accept the beautiful and determined Ms. Li as a bodyguard primarily to appease his publisher. After all, who would want to kill a beat-up, retired ex-spy on a book tour? But when the attacks turn deadly, he soon learns there's more to Madelyn than a pretty face and tempting body. Will the spark become a flame before a killer snuffs it out?
