"An ancient society of cartographer wasps create delicately inscribed maps; a body jacking parasite is faced with imminent extinction; an Al makes a desperate gambit to protect its child from a ravenous dragon; a professor of music struggles with the knowledge that murder is not too high a price for fame; living origami carries a mother's last words to her child; a steam girl conquers the realm of imagination; aliens attack Venus, ignoring an incredulous earth; a child is born on Mars.... The science fiction and fantasy fields continue to evolve, setting new marks with each passing year. For the sixth year in a row, master anthologist Jonathan Strahan has collected stories that captivate, entertain, and showcase the very best the genre has to offer. Critically acclaimed, and with a reputation for including award-winning speculative fiction, The Best Science Fiction and Fantasy of the Year is the only major 'best of' anthology to collect both fantasy and science fiction under one cover."--from cover, p.
