How young do you mean? Ill give you around 3-4th grade though,
Percy Jackson series
Diary of A Wimpy Kid
Junie B Jones
Cam Jansen
Roald Dahl, i really read a lot of his books
he also saved me in reading logs bc reading was rlly easy for me so i procrastinated #procrastinatingsince2008
basic Eric Carle books around Kindergarden...
The Indian In The Cupboard (I think)
Time Warp Trio Series
It was kind of hard but i read the first book of Vladimir Tod when it first came out, lost interest but read few more in 5/6th grade with no problem.
The Magic School bus even though I dreaded it
I read more than that obviously but i cant think of them
