. . Alastair Reynolds burst onto the SF scene with the Arthur C. Clarke Award-shortlisted REVELATION SPACE, British Science Fiction Award-winning CHASM CITY, and REDEMPTION ARK. Now experience the phenomenal imagination and breathtaking vision of 'The most exciting space opera writer working today' (Locus) in these two tales of high adventure set in the same universe as his novels. The title story, 'Diamond Dogs', tells of a group of mercenaries trying to unravel the mystery of a particularly inhospitable alien tower on a distant world; 'Turquoise Days' is about Naqi, who has devoted her life to studying the alien Pattern Jugglers.

    Named an ALA Best Book for Young Adults, Cat's story has been continued by Hugo-award winning and international best-selling author Joan D. Vinge with the very popular Catspaw and Dreamfall. Now, 25 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 for an interstellar government that by turns punishes and helps him, is as fresh and powerful today as it was in 1982.
