A middle-aged historian travels by train to a doctor's appointment. On the way, he slips in and out of sleep, where he dreams of a strange land of fairies. In this world, the young siblings Sylvie and Bruno are caught in the middle of a plot to overthrow their father, the Warden. Sylvie and Bruno is a novel by Lewis Carroll.

Lewis Carroll (1832-1898) was an English children's writer. Born in Cheshire to a family of prominent Anglican clergymen, Carroll-the pen name of Charles Dodgson-suffered from a stammer and pulmonary issues from a young age. Confined to his home frequently as a boy, he wrote poems and stories to pass the time, finding publication in local and national magazines by the time he was in his early twenties. After graduating from the University of Oxford in 1854, he took a position as a mathematics lecturer at Christ Church, which he would hold for the next three decades. In 1865, he published Alice's Adventures in Wonderland, masterpiece of children's literature that earned him a reputation as a leading fantasist of the Victorian era. Followed by Through the Looking-Glass, and What Alice Found There (1871), Carroll's creation has influenced generations of readers, both children and adults alike, and has been adapted countless times for theater, film, and television. Carroll is also known for his nonsense poetry, including The Hunting of the Snark (1876) and "Jabberwocky."
