The highly influential Lovecraft is unmatched when it comes to cosmic horror. The story of "At the Mountains of Madness" is timeless, inspiring and thought provoking - But Lovecrafts writing style is very repetetive and self-referencial. Half the book (or more) is just him repeating himself in slighty diferrent words. Nonetheless, the story itself is so captivating that you forgive it. This is a classic and a must-read for any fan of the genre.
