DD (9), average reading ability, (I think) LOVED LOVED LOVED 'The Mighty Frog' series by Guy Bass, and 'Natboff' by Andy Stanton. And 'Stinkbomb & Ketchup' series when slightly younger.
I think the common thread is the anarchic humour. If your DC also adored these, what else did they find funny and page-turning? Recommendations hugely appreciated...THANK YOU!
