Through the Looking-Glass

Through the Looking-Glass, and What Alice Found There (1871) is a work of children's literature by Lewis Carroll (Charles Lutwidge Dodgson), generally categorized in the fairy tale genre. It is the sequel to Alice's Adventures in Wonderland (1865). Although it makes no reference to the events in the earlier book, 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, uses frequent changes in size as a plot device, and draws on the imagery of playing cards; the second opens indoors on a snowy, wintry night exactly six months later, on November 4 (the day before Guy Fawkes Night), uses frequent changes in time and spatial directions as a plot device, and draws on the imagery of chess. In it, there are many mirror themes, including opposites, time running backwards, and so on. (Wikipedia)
