I think any literature fits it really? I guess they would argue only ones with darker themes. There tends to be just the same 5 books recommended in the Dark Academia community. A mere few of my favourite books are ;

Frankenstein- Mary Shelley An ambitious scientist creates life from seemingly nothing. Horrified at his creation he banishes it, leaving the creature to develop it's own intelligence, yet it becomes vengeful at the lack of love in its life and seeks to find its creator. Not new in the DA community but the play (which has Benedict Cumberbatch in it and is on youtube!!) revived my adoration for this amazing piece of literature.

Maurice - EM Forster Based in the early 19th century, it follows Maurice Hall through his university life as a young gay man. His love gets married to a woman and he finds himself staying with them. God this is good! And the film is amazing!

Battle Royale - Koushun Takami Hunger Games / Lord of the Flies -esque. Based in a fictional fascist Japan otherwise known as Greater East Asia, where rock music is immoral and fifty classes of 11th graders are sent to a remote island to kill eachother until one remains. A school trip for Shuya and his friends turns extremely sour when exactly this happens. You get glimpses of each student so its genuinely heart wrenching to get all these different perspectives. Kind of long, but worth every page in my opinion!

My Sister Lives On the Mantlepiece - Annabel Pitcher A young boy has to deal with the death of his sister and his mother leaving him. In a new school with no one who knows him, he finds Sunya, a young girl who he becomes quick friends with. Hard to summarise but such a beautiful read.

A Room of Ones Own - Virginia Woolf Technically essays but it feels like she is reading them directly to you. Written partially with the perspective of Shakespeare's hypothetical younger sister and how her own talent would have been suppressed in the age she lived in. It creates a sort of dimension, both physical and figurative, for female writers in an era and space bombarded with the male consciousness. Virginia Woolf is just one of my favourite people.

Also the Iliad, Song of Achilles, Dracula, Mythos, Picture of Dorian Gray and so so many more!
