I completely agree with the Geronimo Stilton books. They're fun! Our DD enjoyed them quite a bit. You might consider stopping by your local elementary school and asking the librarian there for some suggestions. Perhaps he/she would have a list of appropriate level books that then could be highlighted with the books that were felt to be of a more appropriate level for your son's sensitivities.

Good luck! It won't be long and most of your concerns over content will not be quite so concerning. smile
