*Sylvie and Bruno* is a novel by Lewis Carroll, published in 1889, with a sequel *Sylvie and Bruno Concluded* (1893). Unlike his Alice books, it intertwines two plots: a realistic Victorian story of romance, society, and moral philosophy, and a fairy tale set in the kingdom of Outland. The elderly narrator drifts between the real world and Fairyland, observing the gentle, loving children Sylvie and Bruno while human characters like Lady Muriel and Arthur Forester explore themes of duty, faith, and selfless love. Though less celebrated than *Alice*, the novel displays Carroll's signature wordplay, whimsical verse, and surprising philosophical depth.
