Someday by David Levithan (hardcover)

Every day a new body. Every day a new life. Every day a new choice.

For as long as A can remember, life has meant waking up in a different person's body every day, forced to live as that person until the day ended. A always thought there wasn't anyone else who had a life like this.

But A was wrong. There are others.

A has already been wrestling with powerful feelings of love and loneliness. Now comes an understanding of the extremes that love and loneliness can lead to -- and what it's like to discover that you are not alone in the world.
