I am fascinated by stories with female con artists and have gathered quite a collection.
Here is my list of romance novels.
I also have lists of con women in:
Non-Romance Novels
Movies
Television
I'm always on the lookout, so if you've read other romances, let me know.
Full disclosure: I have written two romance novels that feature female con artists: Executive Sweet and Rock Con Roll.
