Need suggestions for a 3rd grade advanced reader

Our 3rd grade daughter is reading at a 6th grade level and we would
appreciate some suggestions for reading lists. We prefer story lines that
deal with age-appropriate issues for 9 year-olds rather than with middle
school angst, broken families, etc etc. I know I'm limiting the
possibilities, but hopefully there are other parents out there who feel the
same way. She loves Dear America, Nancy Drew, Babysitter's Club, Little
House on the Prairie, American Girl and the like. All of these we are mostly
comfortable with.

 This is my first posting to the group: please don't flame me. I know that
Babysitter's Club books deal with broken families and I know that the
American Girl series (gently) depicts the death of young children and other
family members. Maybe it's because I'm a dumb 'ol engineer, but I just feel
that sometimes 5th-6th grade level books do not present such topics in a
style appropriate for 9 year-olds. I don't want to get into a debate over
this.

Thanks,
