The Clarion Science Fiction & Fantasy Writers' Workshop at UC San Diego is now taking applications until March 1, 2009. The application form etc. is available here:
This year's instructors are Holly Black, Larissa Lai, Robert Crais, Kim Stanley Robinson, Elizabeth Hand, and Paul Park.
I graduated from the '95 class when it was still held at Michigan State, and I learned a tremendous amount about writing and publishing in my 6 weeks there, and a met a bunch of really interesting, vibrant people. It was a heck of a lot better than any other six weeks I had in graduate school. And as much as I hate that the workshop left the Midwest, I must admit that trading raccoons and mosquitoes for the beach is probably a fair trade ;-)
Anyhow, if you're in a place in your life where you can take off for six weeks and go to California, and if you have tuition money (although they do give out a lot of scholarships), and if you'd like to become a professional science fiction or fantasy writer, Clarion's a good way to go.
