Juggler of Worlds, by Larry Niven and Edward Lerner:
Sci-fi that continues the revisit of Niven's "
Known Space" series begun in
Fleet of Worlds. The main character is a paranoid schizophrenic from the 1960's short stories who ties the newer and older tales of Known Space together nicely. Creative retcons of many of the original stories fill in details of behind-the-scenes manipulations.
(If that review didn't make sense to you, either read the older Niven stuff first, or try to muddle through without a full understanding - there's a dozen books that built Known Space prior to this one. I'm cheating on the three-sentence thing with this note, and by using the Mood icon to convey my overall opinion of the book.)
