Narrative Designer: Fabulator Ludus by Stephen E. Dinehart IV is a deceptively small book. At a little more than 100 pages, it is packed full of very dense ideas on narrative design and storytelling more generally. I will not say too much about it because I feel like it is the type of book that you need to read a few times to reach a better understanding.
But I do wish the book had a glossary. It would have been very helpful!
