How we scored them

The Shelf Score weighs fit for the thriller reader, contents and edition, and value. None of the five listings states a reading age or grade level, so every pick scores zero on that criterion; the ranking comes from the other three. 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 thriller books serial killer fans will finish

Match the subgenre to your taste

A police procedural like Scared to Death follows the detective; a psychological thriller like Memoirs of a Serial Killer sits inside the killer’s head. Love Letters to a Serial Killer mixes true-crime obsession with romance, while Secrets From A Serial Killer is small-town suspense. Pick the point of view you enjoy; the killer is the same, the experience is not. For more twisty psychological picks, see our psychological thriller books.

Series or standalone

Three picks here open a series: Scared to Death is Book 1 of 15, Secrets From A Serial Killer is Book 1 of 5, and Memoirs of a Serial Killer is Book 1 of 2. Starting at Book 1 matters, and the listings number them clearly. If you want one book and done, Love Letters to a Serial Killer lists no series. For series readers, our thriller book series list has more.

Check the format before you buy

Print length is stated for two picks: 368 pages for Love Letters to a Serial Killer and 88 pages for Cutest Serial Killers. The other listings state no page count, so check the format dropdown on the listing. Remember Cutest Serial Killers is a coloring book, not a novel; buy it for the jokes, not the plot.

Before you buy

• Start each series at Book 1; the listings number the series position clearly.
• Check the print length and format on the listing; only two picks here state a page count.
• Read the description for mature themes; every novel here centers on a killer.
