When you think of Hugo and Nebula Award-winning author Robert Silverberg, you most probably think, 'Master of Science Fiction'. Or possibly, even 'Master of Fantasy'. However, what you would most likely never consider is 'Master of Horror'. And yet, there was a time—in the late 1950s—when Robert Silverberg was producing all kinds of science fiction, crime fiction, men's adventure fiction, softcore porn and, yes, even horror fiction! In those days he was turning out an estimated million words a year, necessitating the use of multiple pseudonyms. Many of the stories published in this volume have never been reprinted before—they are drawn from a wide variety of magazines, from Fantastic and Super-Science Fiction to such rarities as Monster Parade and Monsters and Things. In these pages you will find twenty-seven tales by one of the most talented authors in any genre. Featuring vampires, werewolves, ghouls, mad scientists and, yes, monsters and things—both alien and terrestrial—they deserve to be rescued from obscurity.
