David Eagleman's Sum:
Forty Tales from the Afterlives
Synopsis on Wikipedia:
As a work of literary fiction, the book presents forty mutually exclusive stories staged in a wide variety of possible afterlives. The author has stated that none of the stories are meant to be taken as serious theological proposals, but instead that the message of the book is the importance of exploring new ideas beyond the ones that have been traditionally passed down.
The title word "Sum" refers to the Latin for "I am," as in Cogito ergo Sum.
Like Italo Calvino's Invisible Cities, Sum does not fall cleanly under the traditional category of a novel. It has been called "philosofiction", an "experimental novel", and "a collection of thought experiments". Most of the stories are understood to "posit the afterlife as mirroring life on Earth"
