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...
