Posy gets engaged but wants to make sure Matt is the right one for her so she goes back and sees her exes to learn why they did not work out.
Reading the blurbs and ads about this book I was expecting something funny but I found it to be a book that was sad. It was sad that Posy had so little confidence in herself that she could not believe Matt loved her. It was sad that she listened so much to others who did not seem to have her best interests at heart. They (her best friend, sister, and mother) were constantly putting her down because of her past failures. They also questioned why Matt would want her--a perpetual screw-up. Matt does not help when she goes off on her journey of discovery. He gets mad and quits talking to her (although I can understand why.) Both need to learn to communicate better. Posy's mother was--well, I cannot find the words to describe her but she did not build Posy up.
I did enjoy the book though it was not what I expected. I found the epilogue interesting. I enjoy reading Jenny Colgan.
