Literature: Elsewhere

Elsewhere tells the story of a fifteen year old girl, Elizabeth 'Liz' Hall, who who wakes up on a boat headed towards the afterlife. Liz eventually learns that she has died by being hit with a car and is now in the afterlife, where she will age backwards until she is a baby and will then be reincarnated back in the real world. Other than this the afterworld is almost identical to the real world.

Compare Angel Beats!, an anime with a similar take on the afterlife.
