I wasn't sure what to expect when I picked this book up but what an interesting idea. After Piper Willow kills herself, she wakes up at "The Station" where she is giving the choice to volunteer or be sent into the unknown. Volunteering means that Piper will be sent to Earth to inhabit the mind of someone else on the verge of suicide. I sped through this book in around an hour (it's short, sue me) and immediately purchased the next two in the series. Can't wait to see what's next.
