Use of The Glass Castle challenged... a Michigan high school:

It never dawned on Heather Campbell that she'd one day work to get a book banned from a school's curriculum.

But Campbell found herself in just that position after she read Jeannette Walls' memoir "The Glass Castle," a book assigned to her freshman daughter over the summer as part of the 9th grade honors English course at Traverse City West Senior High School.

The complainants are now working to have the book removed from all but the 12th grade curriculum.
