A Fighting Man of Mars is the seventh book in the Mars series, originally published in six-parts in Blue Book Magazine, May to September 1930. It is an interesting and exciting novel filled with futuristic scientific inventions. There are five enemy cities or lands encountered in this tale with five wonderfully drawn villains: Xanator with the green men and white apes; Tjanath with Haj Osis and "The Death"; Ghasta with Ghron the "spider"; Jhama with Phor Tak the mad scientist; and U-Gor with the cannibals. It is a high adventure in the best tradition of Edgar Rice Burroughs.
