I've wanted to read this book for a very, very long time. Well I've now read it, and I loved it. From the first page I knew something was not quite right about Jenna, and discovering the truth behind her accident alongside her is invigorating. There are so many interesting themes to this novel, too. What constitutes a life? How far would you go to save someone you love? How much good can we do, scientifically, medically, environmentally, before we start to do bad? Really fascinating topics, but never does the book feel preachy. They are undertones to a fantastic (light) sci-fi mystery. 
 I also enjoyed the very sparse prose in this book. It seemed to blend well with Jenna's growth and acceptance of her situation. I just wish the novel had been left a little more open-ended. It closes with a bit of a flash-forward epilogue and I'm not sure I wanted to know everything that made up Jenna's life. Sometimes its nice to have a few lose strings left to the reader's imagination.
