Amazon.com Book Description (ISBN 076530340X, Paperback)

When first published, readers young and old eagerly devoured the tale of a street-hardened survivor named Cat, a half-human, half-alien orphan telepath. Named an ALA Best Book for Young Adults, Cats story has been continued by Hugo Awardwinning and international bestselling author Joan D. Vinge with the very popular Catspaw and Dreamfall. Now, twenty-five years later, this special anniversary edition of Psion contains a new introduction by the author and Psiren, a story never before included in any trade edition of Psion. This tough, gritty tale of an outsider whose only chance for redemption is as an undercover agent is as fresh and powerful today as it was in 1982.
