Her Perfect Man (The Man #3)
Nona Raines

Though Kim does her best to shut him down, Charlie's not put off by her attitude. He doesn't scare easy. Kim thinks she's clever, using sex to keep him off guard and to maintain her emotional distance. But Charlie sees through her prickly exterior to her tender heart beneath.
But Kim needs to be won over. Sure, their bedroom action is awesome, but given her past mistakes, she's convinced that Charlie is too good to be true. Just too perfect. But if Charlie has his way, he'll prove that he's the perfect man for her.
