Hidden Charm by Jill Sanders

Mystery writer JT has hidden away from the world on his private island since he published his first novel. Many fans believe it’s because he’s strange or eccentric, but the truth is much darker than everyone knows. After Emma’s very public, very nasty breakup with one of Hollywood’s hottest actors, she needs a friend to lean on. After hitting it off with JT while filming his movie, she takes him up on his offer to let her stay at his secluded place to recover. She hadn’t planned on her troubles following her there, or on being completely charmed by the man.
