Mixed up Files of Mrs. Basil E Frankwiler
Cynthia Rylant has some nice read-aloud books (we especially liked Gooseberry Park)
Harry Potter
Chronicles of Narnia
Half Magic

I really tried to read books beyond their own reading level at that point, as I think it helped with vocabulary. That, and I could stand reading Junie B Jones or the A-Z Mysteries out loud!
