My boyfriend's mum brought this back for me from Sorrento, Italy, because she loved Capri and she knows I love to read (she had no idea of the quality of the book, just thought it would be fun). As she's just gotten back and I've heard all her stories, I 'recognised' (though had never seen except in my mind) many of the places that Kim goes to, and things she sees and does.
As for the storyline itself, it was pretty average. It was a light, fun read although at times there was, among the fluff, some interesting observations about love and life. I felt the most important part of the story was not the affair or love story, but Kim forgiving her mum and her realisation that things aren't always black and white.
