Through the Looking Glass is a sequel of sorts to Alice's Adventures in Wonderland, published seven years after in 1872. Alice, now slightly older, walks through a mirror into the Looking-Glass House and immediately becomes involved in a strange game of chess. Soon, she is exploring the rest of the house, and meets a sequence of characters now familiar to most: Tweedledum and Tweedledee, the Red Queen, Humpty Dumpty, and the Walrus just to name a few.
