My kids have enjoyed The Penderwicks. My son is in 5th grade. There are 3-4 different books.
I’m reading Harry Potter books to them too. (they can read them to themselves, but I am a fan, so don’t mind reading them again)
We liked Rats of Nimh also.
He even liked Matilda.
His favorite book is Spiderwick Chronicles. (I’m afraid he is going to be a fantasy nut like me.)
We did Five children and it too.
We are now starting journey to the center of the earth by Jules Vern
we just finished Thimble Summer and even though it is written from a girl’s POV, he loved the book.
Oh we are in the middle of Little Britches and he is loving that one too.
