A Princess of Mars: John Carter of Mars: Book One

Let the adventures begin, as Captain John Carter finds himself transported to the alien landscape of Mars--where the low gravity increases his speed and strength exponentially. Taken prisoner by Martian warriors, he impresses them with his remarkable fighting skills, and quickly rises to a high-ranking chieftain. But the heroic Carter's powers thrust him right in the middle of a deadly war raging across the planet--and a dangerous romance with a divine princess.
