Coincidentally, I just finished reading "The Children of the Sky", which is a direct sequel to "A Fire Upon the Deep". It's pretty good, though IMO not as good as the original or the prequel "A Deepness in the Sky", which other commenters have mentioned. The Children of the Sky feels... unfinished? As if another sequel is coming. The 3 novels were published in 1992, 1999, and 2011. I wonder if Vinge is working on another one?
