A light and very summery read. Set in a small Cornish seaside town which is idyllic. Two step sisters, Belle and Clemency who make a vow never to encroach on eithers boyfriends, a vow which is hard to keep. It's a funny, crossed wires and misunderstandings kind of book, with no villains, or at least no proper ones. A happy, feel good story with nice, colourful characters - the sort of people you'd like to know yourself, the ones you could have fun with, rely on and fall in love with. Very entertaining, enjoyable, comical and romantic, not to mention a happy sigh at the end - perfect!
