Sorry, I don't have any information regarding Nithya's completed novels, so I can't list any.
Without more context about who Nithya is and what kind of writing she does, it's impossible to list her completed novels. If there were some additional details like her genre preference, the time period in which she writes, or any associated publishers, it would be more feasible to come up with a list.
There are so many people named Nithya around the world. If this is a specific Nithya within a particular writing circle or community, we would need more details. For example, if we knew the region she is from, the language she writes in, or any awards or recognition she has received related to her novels, it would be easier to identify the novels she has completed.
