At the Mountains of Madness

At the Mountains of Madness is a brilliantly told horror novel. Best of all, it's a "perfect" Lovecraft story, combining everything that makes Lovecraft ... well, 'Lovecraftian:' constant impending dread, mysteries beyond time and space, characters driven to the brink of -- and then beyond -- insanity, and science knocking at the doors of the nightmarish unknown.
