The Nebula Awar is an award given each year by the Science Fiction and Fantasy Writers of America (SFWA), for the best science fiction/fantasy fiction published in the United States during the two previous years (see rolling eligibility below). There is no cash prize associated with the award, the award itself being a transparent block with an embedded glitter spiral nebula. The 2007 Nebula Awards were announced on April 26, 2008, in Austin, Texas.
