Book series for 9 year old boy

[BluebellTheDonkey]

He's loved the Switch series and the Beast Quest series, we're wondering what to try next! Any suggestions very gratefully received

How to Train your Dragon series?

Fleabag monkey face

Max Rider.
Narnia Chronicles.
David Baddiels books went down well.
Fortunately the milk by Neil Gaiman.

DS loves Stuart Gibbs - Spy School and Space Camp series.

The Roman Mysteries by Caroline Lawrence are a good series.

For something lighter have a look at the Roman Garstang series by Mark Lowery.

Tom Palmer also writes great books for this age. There is also a good series of football biographies for young readers if he's into sport - I think they are by Michael Part and other authors,

Lemony Snicket.

Thank you for all the fab suggestions I will have a look.
