Hmmm...maybe she might like Eragon? Or Percy Jackson and The Olympians series (The Lightning Thief is book one). There is always The Princess Bride, A Wrinkle in Time, or any of the Susan Cooper books, like The Dark is Rising.

Or what about Roald Dahl - James and the Giant Peach or Matilda.

I can also recommend: So You Want to Be a Wizard by Diane Duane and The Magickers by Emily Drake or the Septimus Heap novels (book one is called Magyk) by Angie Sage.

Good luck!
