"At the Mountains of Madness" is a novella written in serial form, by H. P. Lovecraft in the 1930's.
The story follows a scientific expedition to a range of mountains higher than the Himalayas, in Antartica, where the evidence of ancient species and their society is discovered. The plot is told by William Dyer, a geologist, who writes the story of what he and colleagues experinced, in order to stop a second expedition to the same place.
Without revealing much details, the story develops when the expedition, led by William, finds a few preserved specimens of an unknown species. That by itself isn't overly strange, however they're unlike anything ever found and exhibit a lot more complexity that their geologic age would permit. Afterward, a city of enourmous scale is found which they (William and the expedition) associate to the specimens called Elder Things.
Despite all the set being composed of dead things or ancient monuments, there's still something alive in there (obviously), lurking among them, which of course brings a lot more excitement to the novella.
The style of the story is peculiar, because it is very expository, where the first intent is merely to inform. However as novella progresses, the style turns into a darker object, not merely informative, but also with an intent to scare, as if the writer is reliving the whole experience.
Much of the book is not engaging, because all the descriptions slow a lot the pace of the story. That does have a negative aspect, however all the tidbits of Lovecraftian facts dropped in the story map a quite interesting universe. Where the book is engaging (not as often as I would like), there's almost an overcompensation, where sensations matter a lot (which is usually fear).
For a first experience in Lovecraft, it was an oddly balanced and promising reading. I was certainly enticed to one these days pick up another Lovecraft story.
Recommend, but probably is best to read a couple of other Lovecraft's stories, so you can accustom yourself to Lovecraft's style.
Till next time,
