I picked up this book as part of a project to find really great craft books to recommend to other writers on world building.

DNF at 15% - here's why.

This book is a great summary on how this particular author approaches world building.

The first 9% of this book contains a lot of self-advertising for the series and outlines of what readers should expect to see contained within the pages, instead of jumping right into the pages. But as I skimmed ahead a little, any crafting contained within seemed to be just more links to the authors newsletter - asking readers to give their email in exchange for a template.

I wouldn't recommend it as a craft book, but may be suited best for writers who love to read the different world approaches from other SFF authors.
