I fed Chapter 12: The Battle on the Mountainside into Google Gemini Storybook.  Here is the resulting storybook, and here is the link to the original chat.

Unfortunately there was a glitch, and the image for page 4 of the storybook didn't generate.  (This happens sometimes with Gemini Storybook).  But I'm happy with most of the rest of the illustrations, so I think I'm going to go with this version rather than asking Gemini Storybook to generate again.
