Sylvie and Bruno - Lewis Carroll

The novel has two main plots; one set in the real world at the time the book was published (the Victorian era), the other in the fictional world of Fairyland. While the latter plot is a fairytale with many nonsense elements and poems, similar to Carroll's most famous children's book Alice's Adventures in Wonderland, the story set in Victorian Britain is a social novel, with its characters discussing various concepts and aspects of religion, society, philosophy and morality.
