The Brief History of the Dead by Kevin Brockmeier (2006)Read about another book on the list.
In an accommodating but bland city, the deceased continue to exist, but only as long as someone still alive remembers them. Back on mid-21st-century Earth, things are going dangerously wrong: not least, the rampant spread of genetically modified viruses. If Earth’s population dwindles, what happens to the city of the remembered dead? An intriguing, melancholic portrait of an “in-between” place blossoms into a beautifully lyrical study of memory itself.
