Fox is known as the co-creator of DC Comics heroes Barbara Gordon, the original Flash, Hawkman, Doctor Fate, Zatanna and the original Sandman, and was the writer who first teamed several of those and other heroes as the Justice Society of America, and later recreated the team as the Justice League of America
Aside from that he also wrote 2 Sword & Sorcery series of novels : Kothar the Barbarian and later Kyrik: Warlock Warrior
This is Gardner F Fox’s first paperback attempt at writing a Sword & Sorcery story. There are 5 books in this series. Mr. Fox’s was heavily inspired by Robert E. Howard’s Sword & Sorcery stories: Conan, Kull & Bran Mak Mor. From the world beyond–or past–time Kothar comes. His Sword & Sorcery books read like Dungeons & Dragons campaigns. All they need is a great Game Master to orchestrate the adventure.
From out of the deepest, most violent recesses of mankind’s collective memory, Kothar the gigantic barbarian strides, the enchanted sword Frostfire glittering in his mighty hand. Lusty, hot-blooded, masterful, unafraid of things real or unreal, Kothar dominates the misty, bloody world before recorded time. Yet, though Kothar’s world existed in another age–perhaps another dimension–it springs vividly to life. Mapped, charted, chronicled, Kothar’s fantastic world suddenly becomes real–the sorcerers, dragons, witches, evil potions, unspeakable monsters. And Kothar, an epic hero for any age, overshadows everything.
