Air: Or, Have Not Have by Geoff Ryman will be the winner of the 2005 Tiptree Award. The award ceremony will be held at WisCon 30, to be held in Madison, Wisconsin from May 26 to May 29, 2006.

The James Tiptree Jr. Award is presented annually to a work that explores and expands gender roles in science fiction and fantasy. The award was created in 1991 to honor Alice Sheldon, who wrote under the pseudonym James Tiptree, Jr. By her chance choice of a masculine pen name, Sheldon helped break down the imaginary barrier between "women's writing" and "men's writing." Her short stories were notable for their thoughtful examination of the roles of men and women in our society. The winner was selected from a short list that included:

Aimee Bender, Willful Creatures
Margo Lanagan, "Wooden Bride"
Vonda N. McIntyre, "Little Faces"
Wen Spencer, A Brother's Price
Wesley Stace, Misfortune
Mark W. Tiedemann, Remains
