Vonda N. McIntyre’s Dreamsnake (1978) won the Hugo, the Nebula, and the Locus Award, and reading it today you can feel why — not because it predicts anything, but because it understood something about institutional knowledge that was already true then and has only gotten sharper since.

The novel follows Snake, a healer in a post-apocalyptic American Southwest, who uses the venom of genetically engineered snakes to treat disease, cancer, and infection. Her most valuable snake — the dreamsnake, whose venom produces hallucinogenic visions that help patients confront trauma — is killed early in the book when she treats a superstitious community that panics at the sight of it. The rest of the novel is Snake’s journey to find another dreamsnake before her credibility as a healer collapses entirely.
