While I liked My Life Next Door, her second book fell short for me. Halfway through the book I really didn't see a point for it being written at all. I didn't really feel anything for any of the characters.
Gwen Castle lives on an island in New England and works in her fathers restaurant and with her mother cleaning houses for the vacationers. Its your typical working class girl meets a rich boy, and then they defy what other people think about them. Cass Somers takes a job as a yard boy and suddenly they are constantly running into each other.
The problem I had with this book was that it was way too long without much of a plot happening. Another issue I had was the flash backs. You never knew when they were going to happen and they got a bit confusing.
At the end of the story I took the title "what I thought was true" to mean that Gwen reevaluated everything she thought about her friends, social classes, herself and the relationships she has with her family and friends.
