Madison Stanton doesn't know where she is or how she got there. But she does know this--she is dead. And alone, in a vast, dark space. The only company she has in this place are luminescent objects that turn out to be all the things Maddy lost while she was alive. And soon she discovers that with these artifacts, she can reexperience--and sometimes even change--moments from her life.

Her first kiss.

A trip to Disney World.

Her sister's wedding.

A disastrous sleepover.

In reliving these moments, Maddy learns illuminating and sometimes frightening truths about her life--and death.
