My 7.5 yo DS is a voracious reader and his reading age is 11.5. He reads through a decent length book in a few days, and I am running out of ideas of things for him to read. He has recently been reading through the Roman Mysteries, but I am getting a little uncomfy with the subject matter (kissing and girlfriends/boyfriends)....
What sort of books are complicated enough for him, but also not too 'old' in subject matter?
Thanks in advance xx
