One popular 'weird fantasy horror novel' is 'House of Leaves' by Mark Z. Danielewski. It has a very unique structure and plays with the concept of a haunted house in a mind - bending way.
Another great one is 'The King in Yellow' by Robert W. Chambers. It contains elements of horror and a strange, otherworldly fantasy. The stories within it are often disturbing and filled with an eerie atmosphere. For example, the idea of the play 'The King in Yellow' that drives people mad just by reading it is a very unique and creepy concept.
'Annihilation' by Jeff VanderMeer also fits this category. It takes place in a strange, alien landscape called Area X. The expedition into this area is filled with horror and the unknown. The transformation of the environment and the creatures there is really something out of the ordinary in terms of both fantasy and horror elements.
Some 'weird fantasy novels' worth checking out include 'China Miéville's works. For instance, 'Perdido Street Station'. It's set in a very strange and complex world filled with all kinds of grotesque and fantastical creatures. His use of language and world - building is extremely unique. Then there's 'The Etched City' by K. J. Bishop. It combines elements of fantasy, post - apocalyptic, and the weird in a very engaging way, with a world full of strange ruins and stranger characters.

Chambers, which contains elements of the supernatural and the macabre that are quite strange. And 'Finnegans Wake' by James Joyce is also considered weird. Its language is highly experimental and complex, making it a challenging yet unique read.

Well, 'Coraline' by Neil Gaiman is a great horror fantasy novel. It's about a girl who discovers a parallel world that seems wonderful at first but turns out to be quite terrifying. Then there's 'Pet Sematary' by Stephen King. This novel is full of horror as it deals with the idea of bringing the dead back to life with unforeseen and horrifying consequences. 'The Graveyard Book' by Neil Gaiman is also notable. It's set in a graveyard and has a unique blend of horror and fantasy elements.
One popular 'weird detective novel' is 'The Strange Case of Dr. Jekyll and Mr. Hyde'. It presents a very unique take on the detective story as it delves into the duality of human nature. Another is 'Perfume: The Story of a Murderer', which combines elements of mystery with the strange and grotesque world of a serial killer with an extraordinary sense of smell. There's also 'The City & The City' which has a really weird concept of two cities existing in the same space but with different rules that the detective has to navigate.
Some weird romance novels include 'The Shape of Water' which was also made into a movie. It features a relationship between a human woman and a strange amphibious creature. Then there's 'Gone Girl' which has a very unusual and twisted view of a relationship. It's not your typical love story as it delves deep into the darker aspects of a marriage. Also, 'The Night Circus' has a unique, almost dream - like romance set within the context of a magical circus.
One of the best is 'Alice's Adventures in Wonderland' by Lewis Carroll. It's filled with strange characters like the Cheshire Cat and absurd situations. Another great one is 'The King in Yellow' by Robert W. Chambers. It has a really eerie and otherworldly atmosphere. And 'Gormenghast' by Mervyn Peake is also a top choice. The elaborate and grotesque castle and its inhabitants make for a truly weird and fascinating fantasy world.
One popular office horror fantasy novel could be 'The Devil in the White City' which has elements of horror set against an office - like backdrop of the World's Fair. Another might be 'The Shining' where the isolated hotel can be seen as a sort of 'office' for the caretaker. And 'Dracula' also has scenes that could be related to office - like spaces in a sense, with the bureaucracy and power plays that Dracula has to deal with in his interactions with humans.
In general, they are a niche genre. Most mainstream readers are not interested in them as they often contain content that is considered too strange or not in line with traditional values. However, there is a small subset of readers who are into this kind of very different and edgy erotica.
I would also suggest 'Annihilation' by Jeff VanderMeer. The setting of the Area X is extremely strange and the events that unfold are both terrifying and mysterious. The biologist's journey into this unknown and transformed landscape is full of horror elements that are quite different from traditional horror novels.
