H.P. Lovecraft 
The Whisperer in Darkness [EPUB ebook] 

The Whisperer in Darkness brings together the original Cthulhu Mythos stories of the legendary horror writer H.P. Lovecraft. An Arkham university professor is contacted by a farmer living in a remote part of Vermont, who claims to have evidence of aliens living in the hills and mining a mysterious metal. When local newspapers report strange things seen floating in rivers during a historic Vermont flood, Wilmarth becomes embroiled in a controversy about the reality and significance of the sightings, though he sides with the skeptics. After visiting, the professor becomes alarmed at the mysterious change in the behavior of the farmer, including his assertion that the aliens can extract a human brain and keep it alive in jar for eternity. Wilmarth uncovers old legends about monsters living in the uninhabited hills who abduct people who venture or settle too close to their territory.
