I did a bad thing
Linda Green2007

Sarah Roberts used to be good. Then she did something bad. Very bad. Now, years later, she's living a good life. She works as a local newspaper reporter and lives with her saintly boyfriend Jonathan. She has no reason to think her guilty past will ever catch up with her. Until Nick, the man she was prepared to risk everything for, walks back into her life. And suddenly, what's good and bad aren't so clear to Sarah any more . . .
