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 fantasy world of Fairyland. While the latter plot is a fairytale with many nonsense elements and poems, similar to Carroll’s Alice books, the story set in Victorian Britain is a social novel, with its characters discussing various concepts and aspects of religion, society, philosophy and morality.

This book is the first of two volumes and the two intertwining stories are brought to a close in the second volume, Sylvie and Bruno Concluded.
