All the magic and mystery of fabled India is woven into these marvel tales of seven strange nights. For that vast land which many have conquered and none have subdued is the home of ten thousand gods and a hundred thousand demons — and the teeming races that dwell on its shrouded plains and marbled cities have kept their mystic secrets. Here are hidden gods and demonic possession, here are were-beasts and subterranean terrors, here are beings transformed and souls reborn, here is Terror and Wonder.
