Of all the planets orbiting that G-class star we call the Sun, none was so steeped in an aura of romantic decadence, thrilling mystery, and gung-ho adventure as Mars. This new anthology of all original stories embraces an older, more welcoming, more exotic Mars: a planet of ancient canals curring through red deserts studded with the ruined cities of dying races

Science fiction legend Robert Silverberg reflects on some of his earliest, least-reprinted tales in this new Planet Stories collection! Between 1956 and 1958, Silverberg contributed dozens of short stories and novellas to the digest pulps, each written in the bombastic, high-adventure style of the original Planet Stories magazine. Since then, those tales have re-appeared only rarely (and sometimes never again) in long out-of-print paperback anthologies. This volume, the first of three to come this year, features seven hard-to-find classic Silverberg novellas: Slaves of the Star Giants, Spawn of the Deadly Sea , The Flame and the Hammer , Valley Beyond Time , Hunt the Space-Witch! , The Silent Invaders , and Spacerogue.

Now, forty years later, under the streets of Manhattan an evil genius unleashes the powers of darkness--and Aces and Jokers alike must fight for their lives. Here, in the third volume of the Wild Cards series, seven of science fiction's most gifted writers take you on a journey of wonder and excitement.Includes stories by:Edward Bryant, Leanne C.
