Every Day (Random House Publishing)

A has no friends. No parents. No family. No possessions. Because every day, A wakes up in the body of a different person. A is able to access each person's memory, enough to be able to get through the day without parents and friends realizing this is not their child, not their friend. Because it isn't. It's A. It's a lonely existence--until, one day, it isn't. A meets a girl named Rhiannon.
