Maya asked Cynthia Voigt:

What ages should read your books?

Cynthia Voigt To my mind (which is the mind of a teacher who worked in the 70's and 80's) the Tillerman books are grades 8 and up (although The Runner may be better at grade9 or 10) and the YA others are for grades 9 and up.
Except for Teddy and Co, which is for young children, pre-readers, and the Rosie books, which should work with 2nd graders, I'd say grades 3-6 is about right.
Grade 7 can go in either direction, depending on the reading skills of the child. And Glass Mountain is aimed at adults, by subject not language or event.
I am often surprised at how young some of the students are who have been assigned my books--but then, I have "reading theories."
