The 1974 Booker Prize winning novel, 'Gravity's Rainbow', has a very complex narrative structure. It has a large number of characters and plotlines that are interconnected in a complex web. The themes it explores are also quite deep, such as the role of technology in war and the impact on human nature. Its prose is often dense and filled with allusions, making it a challenging read but also one that offers a lot for those who are willing to dig into it.
Often, they have complex characters. For example, in 'The Remains of the Day' by Kazuo Ishiguro, the butler Stevens is a complex character with repressed emotions and a unique view of life.
These fictions usually have high - quality writing. The language is refined and can create vivid images. Take 'Midnight's Children' for instance. Rushdie's use of language is both magical and thought - provoking, with his unique way of telling a story that spans generations.
