First, I would like to preface this review with the statement: I did not like this book. Not because it wasn't well-written, but because I have certain expectations when reading a book classified as Young Adult / Teen. In a book classified in this genre, I expect a coming-of-age novel or at least some lessons learned about life involving a teen. This book isn't about teens -- it's about centuries-old immortals who act like teens.
In the course of living hundreds of years, our intrepid heroine has been married, had children, done every drug imaginable and has still learned nothing about life. She does decide that she needs to fix her out-of-control lifestyle and ends up finding a home for wayward immortals. I couldn't really get behind any of these people either.
If this book had had just one regular 16-year-old character viewing the strange lives of these immortals, it would have been a much better tale. Half the fun in reading YA is seeing young people learn to grow up and relate to the adult world. Watching a bunch of spoiled immortals just wasn't fun.
