Make sure that every Section of the book has an introductory paragraph

Lauren's recommendation throughout her comments, which I agree with. Introductory paragraphs at the beginning of Sections should just summarize what we will talk about in that section, so that the reader knows what to expect and knows whether to skip it if they are just skimming for information.

Possible idea: Every section has a prettified "blurb" with section title, relevant background sections delineated, and intro paragraph.

Use formatted blurb from emails from CUP people.
