Quite good - a shareware novel. Or possibly novella?
While at John Scalzi's website reading his take on the whole Dubya situation referenced in the last post, I noticed that he had a link to a novel that he had written, and dubbed "a shareware novel". It's called Agent to the Stars, and it's really quite good - a lighthearted character-driven science fiction story, quite funny and even quite touching in spots.
Definitely an enjoyable way to while away a few hours.
