How we scored them

The Shelf Score weighs fit, contents and edition, value, and the listed reading age or level where given. None lists a reading age or grade level, so that part stays at zero. 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 fantasy horror books under 20

Match the horror to the mood

Check series or standalone

Series position changes the commitment. The Librarian book is Book 1 of 12 in a completed series. Check the series number before buying a later book by mistake.

Mind mature themes

Several descriptions deal with death, loss and danger, so preview the premise before buying for a younger reader. For more options, see the best fantasy horror books list, and for lighter horror, see the best middle grade horror books under 10 list.

Before you buy

• Check the publication date, and look for a newer edition.
• Check the series number on the listing, and start with Book 1.
• Check the premise for mature themes before buying for a younger reader.
