Challenged books

I am listening to "The Face on the Milk Carton" by Caroline Cooney. It was on the list published by ALA(American Library Association)of the most challenged books from 1990 - 2000 reported to the ALA. www.ala.org.org A girl of sixteen sees her own face on the milk carton at school and faces the fact that she may have been kidnapped by her own parents when she was just three. Well told, vivid description of her feelings, thoughts, and "daymares" as she finds her memory coming back to her in bits and pieces. It is the first of a trilogy of stories by the same author. I wonder if Caroline Cooney writes under another name in adult fiction. As I am listening I am reminded of Carol Shields book, "The Stone Diary". I usually do not like to read a book written in the first person, but I like the way this is written. I especially like the language that is used. It is quite different and almost poetic.
