At the Mountains of Madness
by H.P. Lovecraft
This Lovecraft classic is a must-have for every fan of classic terror. When a geologist leads an expedition to the Antarctic plateau, his aim is to find rock and plant specimens from deep within the continent. The barren landscape offers no evidence of any life form - until they stumble upon the ruins of a lost civilization. Strange fossils of creatures unknown to man lead the team deeper, where they find carved stones dating back millions of years. But it is their discovery of the terrifying city of the Old Ones that leads them to an encounter with an untold menace.
I really liked this one. H.P. Lovecraft takes his time to set the scene and he does it with such detail that it becomes very real to the reader. It's not a good book if you're in a hurry or looking for a lot of action. You have to take your time with it.
His writing reminds me a lot of classic movies, which rely on shadows and increasing the tension slowly...until you just want to pull your hair out because you know that this discovery is going to be very bad and maybe you don't really want to talk to that old lady in the swivel chair.
