John Scalzi has posted one of his short stories, "How I Proposed to My Wife: An Alien Sex Story". It's being offered as shareware: you can download it for free, but you are encouraged to make a donation through PayPal or Amazon. Half of the money will be donated to The Lupus Foundation of America.
It's a cute story based on the strange and wonderful biology of reproduction. I think it's definitely worth a small donation.
