Plot: I found the plot of this book to be very entertaining and thought provoking. I find the notion of this predicament to be highly enticing. In a way, we can all relate on some level with the situation that Christy finds herself in.
Characters: You know absolutely nothing about the characters in this book, but it is completely imperative to the story that you don't. It adds to the intrigue of the plot and keeps you on the edge.
Themes: As the title itself lends to, the theme of this book is identity. Who are the characters of this book? Who are we all? Sometimes, even if we think we know everything about ourselves, situations and circumstances will force us to really examine if we know who we are at all.
Emotion: As you read, you can feel the panic, fear, and confusion that Christy feels. Since this book is so short, it's not enough to leave you wondering, but it's enough to keep you engaged and connected with the characters.
Overall: This is a nice short read. One that, if desired, you could easily continue on with the series, or let yourself have time to mull over what happened before continuing on. It was a very fast paced book and while it wasn't over involved and the plot was simple, it was an excellent read that keeps you thinking.
First of all DO NOT read this book unless you plan on buying the whole book- this is NOT a complete book but only PART of a whole- and ends in a real cliffhanger. That said I bought the rest of the books (sections) and then the story got weird. It was sort of see through but I hung on to the end and then remembered that I hadn't liked another book of the author's that I had read. The Christian message was good though so I couldn't totally diss this. If you've never read this author before, I suggest you try another one of his books first.
