Winner of the Hugo and Nebula Awards for best novel Four travelers come to the ringworld. . . Louis Wu: human and old; bored with having lived too fully for far too many years. Seeking a challenge, and all too capable of handling it. Nessus: a trembling coward, a puppeteer with a built-in survival pattern of nonviolence. Except that this particular puppeteer is insane. Teela Brown: human; a wide-eyed youngster with no allegiances, no experience, no abilities. And all the luck in the world. Speaker-To-Animals: kzin; large, orange-furred, and carnivorous. And one of the most savage life-forms known in the galaxy. Why did these disparate individuals come together? How could they possibly function together? And where, in the name of anything sane, were they headed?

In her short story collection, Even Greater Mistakes, Charlie Jane Anders upends genre cliches and revitalizes classic tropes with heartfelt and pants-wettingly funny social commentary. The woman who can see all possible futures is dating the man who can see the one and only foreordained future. A wildly popular slapstick filmmaker is drawn, against his better judgment, into working with a fascist militia, against a background of social collapse. Two friends must embark on an Epic Quest To Capture The Weapon That Threatens The Galaxy, or else they’ll never achieve their dream of opening a restaurant. The stories in this collection, by their very outrageousness, achieve a heightened realism unlike any other. Anders once again proves she is one of the strongest voices in modern science fiction, the writer called by Andrew Sean Greer, “this generation’s Le Guin.” At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.
