The series
At a glance.
Six chapter books (Mac Undercover 2018 through Mac Saves the World 2022) framed as a memoir of Mac Barnett's stint as a child spy for the Queen. Illustrated throughout by Mike Lowery in flat, cartoon-strip style; structured around globe-hopping missions; full of digressions, footnotes and asides direct to the reader. Pitched at 7–10 and especially strong for reluctant readers.
Best for 7–10 reluctant readers who want short illustrated chapters, lots of jokes, and a spy mission per book.

Overall tone
- Funny
- Silly
- Adventurous
- Irreverent
Read in order ideally — there are running gags — but each mission is self-contained enough to enter mid-series.

Six missions
Six self-contained spy missions; running gags carry through.
Episodic adventure series with strong reluctant-reader credentials. Each book takes Mac to a new country/situation; the supporting cast (the Queen, his school friends, his mum) is recurring.
