Wow, this one seemed to take a long time. I think Amazon's 317 pages is bogus. Ahh. Found a 384 count. We'll try that. (See how subjective this page count thing is?)
I was expecting this to be a spacey sci-fi novel, but Saturn is actually just the name of the supervillian. The story seemed typical Niven... in that he tended to jump around the plot sometimes leaving me in the dust. And the ending wasn't exactly concrete, so I'm not sure what was supposed to happen next. Still, a halfway-decent read. Er... listen.
