• Examples come from novels, films and television, so the lessons are not limited to one medium
• A single 170-page volume that the description calls a step-by-step guide

Cons

• Independently published, so the listing names no traditional publisher
• Covers world-building in general, so a fantasy writer may want a genre-specific guide too
• The description is mostly promotional, so check the table of contents for the split between craft and examples

How we scored them

The Shelf Score weighs fit, contents and edition, value, and the listed reading age or level. None of the four picks lists a reading age or grade level. How we pick explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.
