Radix is a science fiction novel by American writer A. A. Attanasio, published in 1981.[1] It was nominated for the Nebula Award for Best Novel in 1981.[2] It is the first of four books in Attanasio's Radix Tetrad, followed by In Other Worlds in 1984.[3]

Radix is the story of a young man's odyssey of self-discovery, from dangerous adolescent to warrior, from outcast to near-god, in a far-future Earth dramatically changed from the one we know.[4]

All four books of the Tetrad are being re-issued by Phoenix Pick, an imprint of Arc Manor Publishers.[5]

  • Lotus Face: The name the Serbota tribe give to Sumner Kagan because of a facial scar in the shape of a lotus.
