How we scored them

The Shelf Score weighs fit for the adult reader, contents and edition, value, and any listed reading age or level. Only The Cruel Prince lists a reading age and grade level, so the other four get no reading-level points. 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.
