Query: Great series but probably better suited for 6 to 9 y/o readers

These books are grouped with other books for kids age 8 to 12, however my 7 year old loves the whole series. He has read all the ones our local library has. He started reading them to me when he was 6. Having listened to the stories, I really think that 10-12 year olds probably wouldn't like them. I tried having my son read The Hardy Boys since he seemed to like the mysteries (and our library ran out of The Boxcar Children books). He didn't care for them because the characters seemed too old, to hard for him to relate to. In The Boxcar Children the kids seem a bit younger, at least in how they interact with their world, making it easier for him to relate to the characters. It may be considered in the "reading level" of 8 to 12 year-olds but the content is aimed toward those a bit younger. Even my 4 year old likes listening to them.
