The Nightmare Society is a trilogy of books comprised of 20 short stories each from a variety of different horror writers. The Nightmare Society Trilogy is intended for a more mature audience and is significantly darker than our Nightmare Soup series. Each story was selected for its merits in terror, and is accompanied by a nightmarish illustration from David Romero or Andy Sciazko.
A collection like this is great because it introduces the reader to a variety of writing styles and perspectives, and has something that every horror fan can sink their teeth into.
Standard paperbacks, also include free digital editions.
