What this book is about
Arthur Machen's 1890 novella is one of the most influential horror works in the English language — its premise of a brain surgery that opens a woman's mind to an ancient, amoral reality inspired H.P. Lovecraft and shaped cosmic horror. Unsettling, atmospheric, and genuinely frightening in the way that the best Victorian horror achieves.
