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.
The Shelf Score weighs story, craft, value, fit and availability, as explained on our how we pick page. The Kim Fu leads on awards. The Urasawa follows on epic scope. The Monticello scores for young readers, and the Druid Mysteries for a different kind of mystery.
