How we scored them

The Shelf Score weighs fit for the reader, contents and edition, and value. No reading age is stated for any of the five, so the scores rest on series position and stated facts. 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 series like dark

Start at book one

Three of the five are series starters: Her Dark Secret at book 1 of 5, Once You’re Mine at book 1 of 2 and Tell Me You Like It at book 1 of 8. Dark Greed is book 2 of 10 and Dark Mask is book 8 of 10, so both Charli Cross picks land mid-series. For the full arc, start with a book 1. See our best mystery series latest for more new series.

Mystery or dark romance

Three are straight mysteries: the two Charli Cross books and Her Dark Secret, all with detectives and murder cases. Two are dark romances: Once You’re Mine and Tell Me You Like It, with possessive leads and dark themes. The listings for both romances warn of triggering content. Pick the genre that matches the mood, not just the word dark. See our best mystery series on PBS for more mysteries.

Series length

Series run from 2 books on Possessing Her to 10 on Charli Cross, with 5 on Ivy Bishop and 8 on Legacy of Lies. A short series finishes fast; a long one keeps you in the world. The Legacy of Lies series is complete per the listing, so no waiting for the next book. See our best quirky mystery series for lighter picks.
