How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or grade level. Every pick gives a reading age, and Strangest Mysteries has no grade level stated. 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.

How to choose the best mystery books for teen boys

Match the reading age before the plot

Killing Mr. Griffin lists grade 7 and up with a reading age of 12+, marked as from customers, while The Party lists 16+ with grade 7 to 9. Check both before you buy, since they do not point the same way. For more by level, see mystery books for teens.

Decide between a whodunit and a survival story

Ten and Killing Mr. Griffin are built around finding the killer. I Have a Bad Feeling About This is a survival story with armed killers, so it suits a reader who wants action. For more in that style, browse thriller and mystery books.

• Check the edition: Ten is listed as a Reprint dated September 17, 2013.
• For a series, confirm the book number on the listing before you order.
• Compare the listed grade level and reading age with your teen’s level, since several picks mark age as from customers.
