In 2007, she received the Margaret Edwards Award from the American Library Association for her contributions writing for teens. The ALA Margaret Edwards Award recognizes one writer and a particular body of work for "significant and lasting contribution to young adult literature". Lowry won the annual award in 2007 for "The Giver" (published 1993). The citation observed that ""The Giver" was one of the most frequently challenged books from 1990–2000" — that is, the object of "a formal, written attempt to remove a book from a library or classroom." According to the panel chair, "The book has held a unique position in teen literature. Lowry's exceptional use of metaphors and subtle complexity make it a book that will be discussed, debated and challenged for years to come...a perfect teen read."
