Gullivar of Mars

Quite by accident, Lieutenant Gullivar Jones of the United States Navy is transported to Mars.
Not a barren, lifeless planet, Mars is a lush and beautiful world whose elf-like people embrace him like a brother. To rescue his new bride, the Princess Heru, he quests across the globe to the frosty land of the barbarians who have taken her.
For only he is capable of saving her... and is the only one willing to.
