An entertaining book on Richard Feynman's pranks and interests.
Yep, that along with What Do You Care What Other People Think? and Tuva or Bust!. Plus James Gleik's Genius about Feynmen. I also liked Gleik's Chaos and am currently reading his The Information.
For fiction, I like Alastair Renolds' House of Suns and Vernor Vinge's A Fire Upon The Deep.
