The Gods of Mars

Years after he's been snatched back to the Earth from Mars, John Carter learns how to return to the planet he's yearned for. But Dejah Thoris, the woman he loves, has vanished, leaving him trapped in the legendary Eden of Mars - a paradise from which no one returns. An endearing mixture of Victorian sci-fi and pulp fiction, this is the second swashbuckling story in a long-running series of popular novels set on Mars.
