Query: two stars for encouragement

This book came to me highly recommended, and I really wanted to like it. I just didn't much, however. The plot idea, the killing of a twin, and then the other twin taking over her life, sounded like an interesting mystery idea. But in reality, the characters seemed really 2 dimensional -- totally unbelievable. This might be a good summer holiday book, however, if you don't expect too much. I would like to read some other items by this author -- there is potential for a good mystery writer.
