After reading two books in a row that have no female characters, I think there should be a "list of shame" for books that are otherwise good, but ignore half of humanity (no excuses about historical accuracy, this isn't nonfiction). By "genre" I mean science fiction, fantasy, or horror (and their various derivatives). By character I mean a named female who has meaningful interactions and is more than a cardboard cutout. Let's be loose with that definition in order to keep it in the spirit of the list. If the female wasn't more than a grocery list of traits, a title (i.e. wife/mistress), and a name, she probably isn't a character.

The books don't need to be bad (in fact they can be, in general, good books), just sausagefests.
