Vonda Sinclair might be an author whose works are featured in Fantastic Fiction. It could be that she writes in a particular genre like fantasy or science - fiction.

In my opinion, 'Arrowsmith' is a great Sinclair Lewis novel. It tells the story of a young scientist's journey in the medical field. It's not only about his scientific pursuits but also about his moral dilemmas, his relationships, and his struggle against the commercialization and politics within the medical world. It's a complex and thought - provoking work.
