A place to discuss published SF—novels, short stories, comics, images, and more. Not sure if a book is SF? Then post it! Science Fiction, Fantasy, Alt. History, Postmodern Lit., and more are all welcome here. The key is that it be speculative, not that it fit some arbitrary genre guidelines. Any sort of link or text post is welcome as long as it is about printed / text / static SF material.
