Mary Robinette Kowal was a classmate of mine at the 2005 Orson Scott Card Literary Boot Camp. She's had a pretty charmed literary life since then, I think the first of our class to qualify for full SFWA membership (though Brad Beaulieu might have been there first).
She is definitely the first of us to be listed on the Nebula ballot, and is now on the ballot for the Campbell Award for best new writer. She has definitely found an audience with her work, which is generally well thought-out and edgy.
Please go pay her web site a visit and wish her the best of luck.
