Not knowing the exact nature of 'herta pure fiction', I would suggest looking into the works of Ursula K. Le Guin. She is known for her creative and thought - provoking fictional universes. Her works often explore different cultures, societies, and the human condition within fictional settings, which might be somewhat similar depending on what 'herta pure fiction' entails. Also, the works of Jorge Luis Borges could be relevant. His short stories are filled with complex fictional ideas and labyrinthine narratives that might share some similarities.
As we don't have a clear understanding of 'herta pure fiction', here are some general suggestions. If it has elements of surrealism, you might enjoy the works of Haruki Murakami. His stories often blend the real and the fictional in a dream - like way. If it's more about character - driven fictional stories, then the works of Anton Chekhov could be a good choice. Although his works are often set in a more realistic context, his in - depth character studies and fictional situations can be very engaging. Additionally, if 'herta pure fiction' has a strong element of world - building, then the 'Lord of the Rings' series by J.R.R. Tolkien could be considered, as it has one of the most detailed and immersive fictional worlds ever created.
Since I'm not sure exactly what 'herta pure fiction' is, it's hard to recommend similar works. But if it's a fictional story, you could try works by Neil Gaiman. His books are full of imaginative and unique fictional concepts.
