this thread makes me so happy, as I honestly feel that these are the books that set my Henry's reading path ablaze ♥ He's now reading [at 9] 2-3 of these shorter chapter books and one middle grade chapter book per week.
his hands down ultimate favorites are :
Geronimo Stilton Series [all of them! including the spin off adventures ie: Kingdom of Fantasy, Journey through Time, Spacemice + Cavemice]
Notebook of Doom Series
My Weird School Series [including My Weirder School + My Weird School Daze]
Dragon Master Series ... this is a brand new series [book 3 was just released] that is absolutely wonderful! beautiful illustrations!
Magic Tree House Series
