Two friends on a fishing trip discover a manuscript that chronicles a tale of cosmic horror in the ruins of an oddly shaped house at the edge of an abyss in a remote Irish landscape. The manuscript describes the apparent descent into madness of its author, a recluse who, according to his strange account, witnesses the destruction of the solar system and time itself. The House on the Borderland is a singular work that transcends Gothic-style psychological haunting to introduce a modern, evocative blend of horror, science fiction, and fantasy. This Warbler Classics edition includes the first-edition annotations and a detailed biographical timeline.
