I don't know if the book was intended to be what I would call "feminist horror", but it fits the script: Marian's slow decline as her body stops eating fits the trope of the protagonist in any horror film who slowly goes crazy, leaving the audience to wonder if it is real or imagined. Combine that with a cast of characters who could fit the many tropes of a capital-M Man's view of women (as found in the office virgins, the helpless maiden (Clara), the succubus (Ainsely))-- and other men (a pervasive fear of "queers", the femnized father (Joe), the asexual/inept intellectuals), and you've got a very unsettling novel. However, it is well-written and engaging, and kept me engaged (and a little disturbed) throughout, and the delightfully unsettling climax & denoument made me laugh out loud. Would highly recommend to anybody interested in dark fiction.
