My daughters and I loved Wise Child, Juniper, and Colman (the last in the "series").
Miss B might also like the Jenny Nimmo books about Charlie Bone. Philip Pullman's Dark Materials series -- The Golden Compass, The Subtle Knife and The Amber Spyglass -- would be another possibility.
I will look through our shelves for other possibilities, if you are looking for more ideas.
We love to read around here!
