"Through the Looking-Glass", and What Alice Found There is the sequel to Alice's Adventures in Wonderland. The themes and settings of Through the Looking-Glass make it a kind of mirror image of Wonderland: the first book begins outdoors, in the warm month of May, the second opens indoors on a snowy, wintry night exactly six months later, on 4 November. In it, there are many mirror themes, including opposites, time running backwards, and so on.
