This adaptation of William Hope Hodgson's timeless 1908 horror classic gains new depth and realism through its graphic storytelling in the comic book genre. In this tale of fantasy, science fiction, and occult horror, two backpackers discover the decaying diary of an elderly man in the ruins of an old Irish manor. As they read aloud from the manuscript, they witness Byron Gault's haunting adventures in a hidden cavern beneath his house. Battling cloven-hoofed half-humans and journeying to a parallel reality, Gault, along with his sister and faithful canine, lead a life of horrific supernatural occurrences and eternal terror.
