The Wizard of Oz series is 14 books long; it includes hundreds of characters, plots, and settings. It's easy to forget whose who or what happened. Let BookCaps help with this detailed encyclopedia of Oz. The book gives you a glimpse of Oz's geography, defense system and politics; it also gives a pre-history of how Oz came to be, and gives character summaries for every important character. We all need refreshers every now and then. Whether you are a student trying to cram for that big final, or someone just trying to understand a book more, BookCaps can help. We are a small, but growing company, and are adding titles every month.
