This was an excellent young adult paranormal romance about a fallen angel who has lost her memory and who repeatedly finds herself "waking up" in the bodies of young girls. In this episode, Mercy wakes up in the body of Carmen a sixteen-year-old with a remarkable voice. Carmen is attending an choir exchange and staying in the home of a family whose 16-year-old daughter Lauren was taken with no explanation two years earlier. Lauren's twin Ryan doesn't believe that she is dead and has put his life on hold to try to find her. Mercy agrees to help him. Lauren was a gifted singer too and Mercy is sure that someone involved in the choir exchange had something to do with it. Wonderful first person story. I can't wait for the sequels.
