Book appropriate for a teen about where we go when we die

[The Reading Raccoon]

My friend is looking for a recommendation for a book for her 12 year old son that discusses where you go when you die from DIFFERENT religious points of view. Nothing too scholarly or dry but not a babyish picture book either. And it has to include more that just Christianity.
