DS1 is 8 & school say he has a reading age of 12+ so reading isn't a problem, but age appropriate themes are.
In the last couple of months he's read The Hobbit, all the Percy Jackson books & is now on his last Heroes of Olympus by the same author. He has a library card but also enjoys my buying books for him.
Beast Quest is now too young for him, he likes the original Famous Five but will basically read anything. Any ideas are good thank you :)
