Leigh Brackett - Planet Skaith trilogy

The Ginger Star (The Book of Skaith #1)
Eric John Stark, Outlaw of Mars, travels beyond the solar system for exciting science fantasy adventures on the planet of Skaith, a lawless sphere at the edge of the known universe. Raised as a savage on the hostile planet of Mercury and honed into a fearless warrior in the low canals of the Red Planet, Stark is one of science fiction's greatest adventurers and is Leigh Brackett's most famous character. In The Ginger Star, Simon Ashton, Stark's foster father, has been kidnapped by the Lords Protector, and only Stark can rescue him!

The Hounds of Skaith (The Book of Skaith #2)
More beast than man! Stark had killed the king-dog Flay on the plains of Worldheart. Now he was the leader of the ferocious Northhounds - nine great white beasts that responded to his every command. But should they ever turn on him, the hounds could prove more deadly than any enemy on that hostile planet...

The Reavers Of Skaith (The Book of Skaith #3)
Before Eric John Stark can escape from the dying planet of the ginger star, he is betrayed by the starship captain Penkawr-Che. Abandoned by friends and besieged by enemies, Stark is a fugitive once more. Running from all those who hunt him, he embarks on a nightmare journey through deadly jungles and across predator-infested seas to risk his life for those who hunger for his death.
