I really liked this book, but around the end there were parts where I wanted more. Jenna never told her parents about the hellish purgatory she hints at experiencing while her mind was kept on a computer. There should have been more to that - especially when it came to destroying her back-up and her friends.
From the beginning of the novel, I knew that there was something wrong with her; I thought maybe she was cryogenicly frozen or was a clone. I was impatient to get to the part where she figured it out, but I didn't think it was slow at all. It's too bad that the epilogue takes away possibilities for a sequel.
I particularly liked Jenna's description of her love for physical books. And in the future!
