"Through the Looking-Glass" is a novel written by Lewis Carroll, published in 1871. It serves as a sequel to the famous story "Alice's Adventures in Wonderland." The narrative follows Alice as she steps through a mirror into a fantastical world where everything is reversed, including time and logic. In this new realm, Alice encounters a variety of peculiar characters, such as the Red Queen and the White Queen, and engages in whimsical adventures. The story explores themes of identity, language, and the nature of reality, often using playful wordplay and nonsensical elements that challenge conventional thinking.
