While not totally unfamiliar with Greg Egan – I’ve read the brilliant Schild’s Ladder, and his early Quarantine – I did start Incandescence with the wrong expectations.
The blurb of the British 2009 Gollancz paperback promises something akin to space opera:
“A million years from now, the galaxy is divided between the Amalgam, a vast, cooperative meta-civilisation, and the Aloof, the silent occupiers of the galactic core. The Aloof have long rejected all attempts by the Amalgam to enter their territory, but travellers intrepid enough can take a perilous ride as unencrypted data in their communications network, providing a short-cut across the galaxy’s central bulge.
Rakesh has waited all his life for adventure to come calling. When he meets a traveller who claims she was woken by the Aloof mid-journey and shown a meteor full of traces of DNA, he accepts her challenge to hunt down the uncharted world from which the meteor came, deep in the Aloof’s territory.
Roi and Zak live inside the Splinter, a translucent world of rock that swims in a sea of light they call the Incandescence. They live on the margins of a rigidly organised society, seeking to decipher the subtle clues that might reveal the true nature of the Splinter. In fact, their world is in danger of extinction, and as the evidence accumulates, Roi, Zak, and a growing band of recruits struggle to understand and take control of their fate.
As Rakesh gradually uncovers the history of the lost DNA world, his search leads him to startling revelations about the Splinter – and the true nature and motives of the Aloof.”
I’ve quoted it in full, because it is striking because of two things: Egan’s own rigorous ethics concerning book jackets (see my review of Schild’s Ladder for the full anecdote), and his scathing reply to a review of Incandescence by Adam Roberts in Strange Horizons. Let me try to explain, and provide my own review of sorts by doing so.
