I thought this book was a lot of fun. I always wanted to get back to it so I could find out what happened next. I liked the way it was told in 'before' and 'after' sections, so you see where she ended up and then go back to figure out how she got there. There is adventure and danger and excitement, but it also makes the reader think about what makes you, you. It presents a lot of questions about identity without becoming overly philosophical to the point that it interferes with the flow of the story. There are some things that happen that don't seem to have any logical (or any other) explanation. And there is a scene (a rather long one) that seems to have nothing to do with the plot. But I have to admit it didn't bother me at the time of the reading. I assumed it would all come together at the end. I was only disappointed when it was over and things that I felt needed to be explained were not explained. It had a couple of hiccups, but I still found it enjoyable and would be interested in reading more by Kirby.
