I reread books all the time as a kid. I just made emotional connections to certain characters (To Kill a Mockingbird, "advanced" Judy Blume books, Anne of Green Gables series, Sweet Valley High - ahem - wait).

What about introducing her to short stories? There are so many wonderful classics written at higher levels of reading which require more insight into metaphor, foreshadowing, complex character motivation. The best part is they are snippets of a challenge vs sn entire novel. Maybe that could be an afterschooling project?
