Please check the Mensa for Kids website. I remember comparing it to the average Reading Olympics reading list that you might find in the library and the Mensa list did seem better geared to the advanced reader.
Also, find a librarian that you love in or around your area and pick their brain. They know all of the books hopefully old and new or the person in charge at your favorite book store.
There are big time readers out there you just have to hunt them down. Happy Reading! (My little one was a science buff at that age so we were not on top of the mystery genre.)
