Book I read: Building Harlequin's Moon

I read Building Harlequin's Moon over the last few days and enjoyed it very much. 

I love sci-fi in general and Mr. Niven's writing in particular.  This and Ringworld are in the running for my best reads of the year.

Ironically I try to avoid reading Mr. Niven's short stories.  They always leave me wanting more!  He's the king of "Open to sequels."
