How we scored them

The Shelf Score weighs fit, contents and edition, value, and reading age or level where given. No pick states a reading age or grade level. 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 spy novels with female leads

Start with the lead, not the series

The Thistles lead is named in its title as a female spy and private investigator, and the Rufus lead is an apprentice healer who travels north while an assassin follows. The title-only picks name a librarian spy and a spy school, so check their listings for lead details. A mystery novel with a female protagonist list offers more leads.

Series position matters

Thistles is Book 1 of 4 in Pistils, so it starts a series, while The Rufus Spy is Book 8 of 10 in Aelf Fen Mysteries. A series start is easier to enter than a mid-series book. The title-only picks state no series position.

Check the format and date before buying

Thistles is an introductory novella, not a full-length novel, and the listing states that the novella is just over 60% of the book, with the first four chapters of the next novel as the remainder. Dates run from June 22, 2018 for Thistles to April 23, 2026 for The Rufus Spy. A spy novel for young adults list covers younger readers.

Before you buy

• Check the series position, and which book comes first.
• Check the publication date and edition.
• Check the page count and any reading age or grade level.
