From wikipedia:

Through the Looking-Glass, and What Alice Found There (1871) is a work of  literature by Lewis Carroll (Charles Lutwidge Dodgson). It is the sequel to Alice’s Adventures in Wonderland (1865). 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 (May 4),[1] 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),[2] 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.

There are only 12 chapters numbered from 1-12. and you can click on the diagram for a closure look.
