IMHO Marooned in Realtime is the best Vinge book. Besides being a dual mystery novel, it really explores the implications of bobble technology and how just a few hours of technology development near the singularity can be extreme.
On a second read, when I knew where the story was going and didn't need the frisson of resolution, I enjoyed it much more. It's good B & C plot, and it all does tie in. But arguably the pacing is off.
I later read the prequel and did not like it. I never read the third book in the trilogy.
