This month's book club selection is Permutation City by Greg Egan.
It's ok to attend if you didn't finish or read the book, but spoilers, including the ending, will be discussed.
I'll post the link about a day before.
From Goodreads:
The story of a man with a vision—immortality: for those who can afford it is found in cyberspace. Permutation City is the tale of a man with a vision—how to create immortality—and how that vision becomes something way 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.
