Joy to the world . . . or, joy to the worlds! Let heaven and nature—and also the supernatural—sing. A Cosmic Christmas presents twelve stories of Christmas in very unusual circumstances, ranging from vampires to robots, from the hills of Appalachia to a high orbit space station, all celebrating the holiday in their own, off-beat ways.

New York Times best-selling author Larry Correia sends his popular tough guy detective and magicwielder, Jake Sullivan, on a special case at Christmas time, while visions of tommy guns dance in the heads of the thugs he's up against. Mark L. Van Name's Lobo, an A.I. housed in a pocket battle starship, drops his usual cynical pose to help a troubled family at Christmas time. Nebula Award-winner Catherine Asaro tells of a romantic Yuletide weekend that turns into a mystery in a futuristic high-tech house. New York Times best seller Mercedes Lackey offers a Christmas ghost the likes of which Scrooge never encountered. George O. Smith, a star of the Golden Age of science fiction, is on hand with an episode from his classic Venus Equilateral series, in which a Christmas celebration on a gigantic space station is interrupted by the arrival of a ruthless interplanetary criminal, who didn't drop by to hand out presents. And much more, in a holiday package that any fan of science fiction and fantasy would be delighted to find under their tree, on any planet.
