I burned through this book in a day and a half - compulsively readable. It reminded me a bit of The Time Traveler's Wife, a bit of one of my absolute favorite books, My Name Is Memory by Ann Brashares mixed with the old tv show Quantum Leap. The main character (of indeterminate gender) wakes in a different body every day and is desperate to keep his (her?) connection the person he (she?) has fallen in love with; as you might surmise, there are some interesting themes about gender and love. Very cool book, I just felt that the ending was abrupt and cryptic.
