As noted before, definitely not the strongest of Zelazny's work. But what a fun little read - these are short stories compiled into one book and they're creative and full of fantasy favorites - vampires, demons, summoning, etc. etc. You'll fly through this - I read it in two days!
Not the best Zelazny, by any means. Collection of short stories centred on Dilvish, recent escapee from Hell, and his companion, a demon in the shape of a black metal horse. Lightweight.
An enjoyable sword-and-sorcery book, half-elf Dilvish and his demonic steel-bodied horse Black were originally published in a series of short stories in the 60s; this is an anthology of those stories, along with three new ones to fill it out. Dilvish is a hero with a difference, who uses small bits of occult knowledge, a fine grasp of tactics, and a skill with swords to try to find the sorcerer who wronged him.
