Common categories on Jeopardy focus on general topics such as history, geography, literature, food & drink and sports & entertainment. Other categories might be more specific, focusing on history of a certain country or an entire category devoted to one famous person. Then there are the novelty categories such as "Rhyme Time", "Names the Same" and "Stupid Answers."

You should start your Jeopardy Board with a decision on the different categories that you will be using. You said it was a book and not a group of books or a category or series of books. It will be hard to find many categories with 5 questions in each category about a book, when you will need 6 categories for each round. You might start with a Wikipedia search on the book title. You can pick some of the characters in the book that you can also find 5 questions to ask and make them categories for your Jeopardy board. You might ask questions about the author in another category. Locations and events in the book can also be used as categories. Jeopardy uses facts to ask a question that lead to the answer. You can review and even search with a keyword an archive of the Jeopardy shows at the related link.

Jeopardy has a team of writers and researchers for the questions and categories. Feel free to contact them because they will decide if your category suggestions have merit regardless of what was done previously.
There are six categories, each with five clues ranging in values of $200, 400, 600, 800 and 1000 in the Jeopardy! round and $400, 800, 1200, 1600 and 2000 in the Double Jeopardy! round. Final Jeopardy! has its own "board", the flat screen monitor that stands to Alex's left. Usually, but not always, the last column in each round contains a tongue-in-cheek category such as Rhyme Time (often requiring more wit than specific knowledge of a subject.)
