I love Kafka too. I was thinking I hadn't read The Process, then I realised this was just a different way of translating the title of the novel that I know as The Trial.Maybe I'll write a more elaborate list of my favorite authors, but currently, I've been focused on write short narrative stories of fantasy,so I'm mesmerized with Edgar Allan Poe (I love the Morgue street story and Eleanor. I also love "The raven" and Annabel Lee). Kafka is also an author I've read a lot lately, "The process" is my favorite story.
There is a brazilian writer that I wish that people could learn more about her,that is Clarice Lispector: she writes beautifully her tales. Machado de Assis is another braziliam author that I've wish people could learn about him, I love his "fancy irony".
These days,I've read a very nice tale of Nathaniel Hawthorne named " The young Goodman Brown" ( I think this is the title in English) and I was hooked up. I'm looking for more fantastical tales to help on my research to write.
I've only read snippets of Lispector when she's quoted by the likes of Hélène Cixous.
In terms of short narratives of fantasy, do you like the stories of Borges? Some of his poems are also short, fantastical narratives. Usually with a philosophical dimension.
I tend to be drawn to prose poetry or short fiction that could pass as prose poetry, such as Lydia Davis.
