Why does an old boyfriend seem so much more attractive when you haven't seen him for years?Have you ever wondered what your ex is up to?When Nell was a student, she and Patrick were a serious item. They were inseparable, and she really thought he was The One. But then Alex came along...the safer, more restful option, and thanks to her over-controlling mother she opted for him instead.Now nothing is going right. Alex has left her to live in New York with a younger, blonder woman. Escaping to the Caribbean for a recuperative holiday, she is mugged at Gatwick and her bag is stolen. It's crisis time - and she makes two decisions: First - she will take lessons in self-defence. Second - she will try and find Patrick again. Is she trying to put the past behind her - or setting out to ruin her future?
