I read little bits of everything. My mystery preference is cozy. I enjoy science fiction, but do not have a science background. And I'm a hobbit from wayback before I was old enough to vote.
                     
                                       
                                             OMG, as a writer David Levithan's books are either hit or miss.  However, this one was a huge hit.  We know very little about the main character A, including what sex the character is.  We do know A is 16.  A is a jumper each morning A wakes up in a different 16 year old's body.  The journeys A takes with each teen are sometimes mundane, but sometimes very powerful.  This is a great book to try and help teens understand what empathy is and what walking a mile in someone else's shoes is actually like.  My only regret is I can't reread this book for the first time.
