Orson Scott Card is one of the biggest names in science fiction and fantasy. He won both the Hugo and Nebula science fiction awards for best novel for two consecutive years - something no other writer has done. In addition, he was the first writer to ever win a Nebula and a Hugo for both a book and its sequel.
YA-- Card does not discuss how to write in general, e.g., plotting, style, dialogue, point of view, or characterization, but instead covers creative writing as it relates to the science fiction/fantasy genre. He includes such diverse topics as inventing a world, creating alien societies, the rules of magic, etc. This well-written volume is an excellent resource for beginning writers or a refresher for those already on their journeys to other worlds and other stars.
