If you enjoyed A Fire Upon the Deep, you should definitely check out the other 2 books. The Children of the Sky is a straightforward sequel to A Fire Upon the Deep, more fun with the pack intelligences of the Tines. I really liked the idea of a pack intelligence surviving longer than an individual member in those books. A Deepness in the Sky has a hibernating technological spider civilization and human savants exploited and enslaved as basically hyper focused biological automatons. Also there are inflatable space ships. Working my memory to type this, I realize that I kinda want to read them again.
