    Delany's 1976 SF novel, originally published as Triton, takes us on a tour of a utopian society at war with . . . our own Earth! High wit in this future comedy of manners allows Delany to question gender roles and sexual expectations at a level that, 20 years after it was written, still make it a coruscating portrait of the happily reasonable man, Bron Helstrom -- an immigrant to the embattled world of Triton, whose troubles become more and more complex, till there is nothing left for him to do but become a woman. Against a background of high adventure, this minuet of a novel dances from the farthest limits of the solar system to Earth's own Outer Mongolia. Alternately funny and moving, it is a wide-ranging tale in which character after character turns out not to be what he -- or she -- seems.

    Up the Walls of the World is the 1978 debut novel of Alice Sheldon, who had built her reputation with the acclaimed short stories she published under the name James Tiptree Jr. A singular representation of American science fiction in its prime, Tiptree’s first novel expanded on the themes she addressed in her short fiction. Known as the Destroyer, a self-aware leviathan roams through space gobbling up star systems. In its path is the planet Tyree, populated by telepathic wind-dwelling aliens who are facing extinction. Meanwhile on Earth, people burdened with psi powers are part of a secret military experiment run by a drug-addicted doctor struggling with his own grief. These vulnerable humans soon become the target of the Tyrenni, whose only hope of survival is to take over their bodies and minds—an unspeakable crime in any other period of the aliens’ history...

    A stunning collection of the kind of fiction that has only one source--the unparalleled Ray Bradbury.
