A Deepness in the Sky by Vernor Vinge (Zones of Thought series)

My fourth Vernor Vinge novel (on loan from ), and a good read.

A mindrot disease, a strange star cluster, a race of intelligent spiders, interstellar traders, dustmote computers… good stuff.

Somewhat of a jillion-year prequel to A Fire Upon The Deep. One of the characters in Fire was a god/computer-reincarnatation of a character from Deepness.

Good page-turner.
