The Ultimate Vampire Resource and Directory

A death duel on the shadow frontiers of the mind. Cat-he's the ultimate half-human punk. Tough. Cool. Solitary. And a telepath. Orphaned on the killing streets of a distant planet, Cat uses his psionic talent to evade the labor gangs and security police. But now he is swept into the midst of an interstellar power struggle. Both sides want to use his mind...as a weapon. Cat owes no loyalty to a Federation government. But there's no neutral zone. If he doesn't fight, Cat-and all he cares about-will be destroyed. To save himself, Cat must go undercover against a militant psi warrior-an enemy who can read his mind.

This special 25th 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 for an interstellar government that by turns punishes and helps him, is as fresh and powerful today as it was in 1982.
