Psion

Joan D. Vinge · first published 1982 · ISBN 9780765303400

Cat is a young telepath living on a mining colony deep in space, marked as an outcast because of her half-human, half-Hydran genetics. When a corporate faction needs her telepathic abilities for a dangerous mission, she's forced to choose: work or face deportation. The job throws her into corporate espionage and forces her to confront her own identity and whether she can trust anyone around her.
