Before men emerged from the primeval jungles, might not other beings have dominated this planet, utilized it, contacted the stars, and called Earth theirs? Brian Lumley has now seized the eerie torch lit by Lovecraft and Derleth, and fires us a new edge-of-the-seat science fiction horror novel of the investigators who dared disturb the hibernation of the world's real landlords.
