Over and Over

Imagine that you wanted to write more than one book on the same topic, and had to figure out a way to legitimately stretch the topic out over multiple volumes while making sure readers feel they’re getting their money’s worth. First, pick a topic that you know something about. You don’t have to be an expert, but you should at least be moderately well-versed in it, and capable of researching what you don’t know. Brainstorm the various sub-topics you might tackle, the kind of mileage you could get from them, and how many books you might be able to stretch them out across.
