Pratchett explores the questioning of identity through Tiffany's development as an adolescent and as a witch as she comes to terms with wanting to be part of Annagramma's group of witches but not wanting to become just another sheep within that group, while developing herself as a witch and taking control of her life (as well as her mind), when the hiver tries to take her over. Tiffany is on the brink of adolescence and is becoming "more conscious of image" of both herself and the world.

The central theme in this book and the followup The Wintersmith, is 'coming of age' which is coupled with all the associated ideas of that theme the question of identity, self sacrifice and responsibility.
