Greg Egan 
Permutation City 
The incredible, mind-bending look at cyberspace, afterlife and immortality from one of the greats of science fiction

Immortality can be yours . . . at a price Permutation city is the tale of a man with a vision – how to create immortality – and how that vision becomes grows beyond his control. Encompassing the lives and struggles of an artificial life junkie desperate to save her dying mother, a billionaire banker scarred by a terrible crime, the lovers for whom, in their timeless virtual world, love is not enough – and much more – Permutation city is filled with the sense of wonder and dread. Can what makes you human be distilled into data? And what happens if you can’t afford to pay?Readers are having their minds blown by PERMUTATION CITY:"Egan tells the story masterfully.

THIS is the sense of wonder I’m looking for in a SF story. Forget everything you read about virtual reality, artificial life & consciousness – nothing compares to the concepts and the worldbuilding in this book. This is ultimate postcyberpunk ever" – Goodreads reviewer, "I can say without qualification that Greg Egan is the greatest science fiction author I’ve ever read" – Goodreads reviewer,
