Take Me Home! A Princess of Mars by Edgar Rice Burroughs
I opened my eyes upon a strange and weird landscape. I knew that I was on Mars; not once did I question either my sanity or my wakefulness. I was not asleep, no need for pinching here; my inner consciousness told me as plainly that I was upon Mars as your conscious mind tells you that you are upon Earth. You do not question the fact; neither did I.
So reacts John Carter, ex-cavalryman of the Army of Northern Virginia, when he transmigrates to the red planet in A Princess of Mars (1917). Chased by torture-minded Apaches, Carter secrets himself in a cave. By unknown means, he finds his spirit severed from his body and transported to Mars.
On Mars, a dying, barren world littered with the ruins of millennia-gone civilizations, he finds his great love and becomes the greatest hero that Barsoom, as its inhabitants call Mars, has ever known. Along that path to glory, thousands of miles are traveled and thousands of foes slain. A Princess of Mars is pure escapist fantasy, where the protagonist, standing in for the increasingly civilized American man Burroughs was writing for, fights and defeats all foes, outwits every enemy, and wins the hand of the most beautiful woman in the world. To some, that might sound juvenile, but they are wrong. A Princess of Mars is absolutely deserving of the mind-blowingly pulpy cover illustrations of Frank Frazetta.
