How we scored them

The Book Score weighs performance (thriller craft), build (series depth), value, safety and warranty. For thrillers, safety means a stated reading age: The English Assassin lists 18 years and up, so it earned safety points. No listing states a warranty term, so all scored zero there. 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.
