The Great God Pan
Lake Arcadia: A Sex-Magic Novel is tangentially inspired by The Great God Pan, a novella by Welsh writer Arthur Machen, who inspired much of H. P. Lovecraft’s writing. Stephen King described The Great God Pan as “Maybe the best [horror story] in the English language.” I wouldn’t go that far, but it’s worth reading.
To be clear, Lake Arcadia isn’t at all horror. In fact, it’s fairly lighthearted, but inspiration can come from the strangest places.
