H. P. Lovecraft 
At the Mountains of Madness, The Call of Cthulhu and The Music of Erich Zann [EPUB ebook] 

This H. P. Lovecraft trilogy represents the best of Lovecraft’s writing.
At the Mountains of Madness was initially rejected by Lovecraft’s publisher but is now considered a classic by horror fans. The disturbing, nightmarish story of a journey through Antarctica and a discovery of secrets hidden in a frozen mountain range has influenced writers and film-makers for decades.
The Call of Cthulhu is a terrifying trilogy of horror stories that has influenced writers like William S. Burroughs, Ramsey Campbell, Thomas Ligotti and Stephen King.
The Music of Erich Zann is a short story, one of Lovecraft’s finest.
