Having returned from holiday with more books (see Greenflame: Back from holiday (with books)) we all went out a few days back to one of the local secondhand bookshops with a box of books to exchange. A successful trip with all 6 of us finding something amongst the volumes. To my delight I picked up a copy of Diamond Dogs, Turquoise Days by a favourite author of mine, Alastair Reynolds.
Reynold’s ‘Revelation Space’ explores, among other things, how human society might shape itself with different responses to technology interfacing with the human body. As such it is a good example of transhumanism in fiction. Wikipedia has an article on transhumanist fiction as a genre, including links through to some works that are available for download.
