The list author says: "I am creating this list from a sense of obligation to completists. I didn't much like these books but some readers have to have it all. Some books, like The Eden Retrieval, go in and out of availability so fast that they can't be maintained on a Listmania List."
"Let me know if you can make sense of this dreadfully poor effort. The dialogue is a joke, the sex is puerile, the biology is questionable and the physics is delivered in tedious lectures. Cthulhu and Yahweh are brothers. No, I am not kidding. Like some other real dogs here, this is a self published book from a vanity press."
"Decent if not particularly compelling sequel to the Innsmouth story. Mixing ghosts and Deep Ones did not work at all for me. For a better mythos read, try the novels of Brian McNaughton. For a worse read, well check out the other books on this list."
"Of passing interest to mythos fans due to it's take on the supernatural twins plot device from The Dunwich Horror and references to Yog Sothoth. Be prepared for a heavy dose of pornographic sex. I guess a true devotee will get the preferred text, Gemini Rising, in the Wildside Press edition."
"To be fair, I only ever skimmed this book after reading the author's preferred (and more expensive) version, Downward to Darkness. This is not pornographic, like Satan's Love CHild and may serve as a budget alternative to fans interested in McNaughton."
"You get the idea. Those of you taking the high road will get Worse Things Waiting from Wildside Press. Others can score a used copy of this. As above, I did not read Satan's Seductress but only skimmed it. In the cursory look I did not think it was pornographic, like Satan's Love Child."
"Only dedicated collectors need apply. About half the stories are neither Cthulhu mythos nor Lovecraftian. Dominion by D'Ammassa and The Psychopomp of Irem by Pugmire, however, as far as I know are unavailable elsewhere."
"This is not a Cthulhu mythos book in any sense. These are stories for readers who want feel good Christian literature; Cthulhu is mostly just another aspect of Satan. This misses the whole point of Lovecraft's fiction. Well written and engaging but completely off topic."
"Pretty weak. Mr. Landri uses the names Cthulhu and R'lyeh, and some of HPL's imagery, but that's about it for anything approaching Cthulhu mythos horror. Cthulhu makes a pitiful appearance as a villian with completely anthropomorphized motivations in what amounts to a comic book without the diverson of pictures."
"I am sorry to include a book by an author of Mr. Wolfe's stature on this list, but I found An Evil Guest to be a disjointed mess without coherent plot or theme. Too bad, it could have been so much more."
"This is not a bad book; in fact, Mr. Spencer's prose is quite good. However, I do not want the unwitting to think this is a Cthulhu mythos story per se. Instead HPL's creations are used as manifestations of the main character's psychic distress. More for students of HPL's influence on popular culture instead of horror fans looking for a Cthulhu fix."
