How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the publication date where one is given. 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 with female protagonist

Procedural, thriller or cozy

Three of these are procedurals and thrillers: Tracy Crosswhite is a Seattle detective working a cold case, Olympia Smith is an FBI special agent in a bank robbery thriller, and Indie Reign is a detective with a K9 partner on a gruesome case. Two are cozy: Flora Steele is a bookshop owner turned amateur sleuth in 1956 Sussex, and the Paradise Florida Keys series opens with an inheritance and a body count in Tarpon Cove. Pick the tone first: a reader who wants grit and a reader who wants charm are different readers.

Mid-series or series starter

Four of these are mid-series: Book 12 of 13 for Tracy Crosswhite, Book 4 of 5 for both Mary Stone series, and Book 5 of 15 for Flora Steele. One is a series starter: Crazy in Paradise is Book 1 of 38, the entry point to a long series. Mid-series books read best after the earlier ones; a Book 1 lets a reader start clean. For more standalone options, see our mystery novels with female protagonists list.

Police, FBI or amateur

The leads split by badge: Tracy Crosswhite and Indie Reign are detectives, Olympia Smith is an FBI agent, and Flora Steele and the Tarpon Cove lead are amateurs. A professional lead brings procedure and jurisdiction; an amateur brings curiosity and charm. The K9 partner in Buried Reign is a bonus for readers who like dogs in their mysteries.

Before you buy

• Mid-series books read best after the earlier books in the series.
• Match the tone: procedural grit or cozy charm.
• Book 1 of 38 is the clean entry point here.
