Ken Jennings, the host of Jeopardy, wrote an interesting and amusing book. It's a tongue in cheek look at the various afterlives awaiting humanity. The gamut runs from Mythology (Valhalla, Hel, Kur, Duat, etc.), to Religion ( Gehenna, The House of Song, Summer Land, etc.), to Books (Adams County, The Cemetary, paradise, etc.), Movies (Bogus Journey, Canine Heaven, The Undying Lands, etc), television (The Black Lodge, oceanside, Robot Hell, etc.), Music and Theater (The Afterlife, Hadestown, Up There, etc), and Miscellaneous (The Eight Underworld, The Land of the Unliving, Hellscapes, etc).
Each entry will show where the story came from and what it is like to be there. Depending on the setting, some have interesting tidbits like "Things to See" or "Places to Visit" that will highlight the strange sights of the Afterlife.
A fun, and enlightening, look at the various interpretations of the Afterlife in popular culture, history, and religion. While not a very scholarly read, it is fun and it does provide a brief look, albeit in a humorous form, at the various Afterlives imagined by humans.
