Hugo voting deadline is tonight at 11:59 PDT.
The novella category is very strong, but I think Geoff Landis's "The Sultan of the Clouds" clearly leads the field in all the virtues of classic science fiction. You may well have read it, since he's my husband, and if you know me, you probably know him. But just in case you haven't. you have just time to read it before the deadline. It's at www.geoffreylandis.com/Sultan.pdf.
In case you think I'm prejudiced, consider that maybe I married him because he had the soul to write this story with all the elements of great science fiction, including not just accurate and amazing science and plot twists, but also an account of thwarted love, plus a fabulously believable and vital woman character.
Partly. He had other virtues, too.
In any case, whether you favor his story or another, please vote.
