My DD10 reads at 12+ level (highest they test to in elementary) and she just got the highest AR number/percentage ever in her entire school.

She did about 465% of her AR goal this year.
Some of her favorite series, when she was younger, have been:
Harry Potter (started reading in 1st grade),
Little House (this was in 3rd grade),
Lemony Snickett (also in 3rd),
Animorphs (hard to find-out of print), &
Chronicles of Narnia. In 4th grade it was all about
Percy Jackson which got her interested in Greek Mythology. She is currrently reading the
Warriors Series (yes by Erin Hunter by actually 3 different writers, so my DD tells me) which she really enjoys since it's all about cats.
She's never been interested in books like The Babysitters Club, etc.
A year or two I gave her my old copy of "My Side of the Mountain" She liked it.
Good luck-finding new series of books for a voracious reader is not easy!
