This year marks the 25th anniversary of the Margaret A. Edwards Award, given by the Young Adult Library Services Association in honor of work that makes a “significant and lasting contribution to young adult literature.” The award, which is sponsored by SLJ, was presented Saturday to Tamora Pierce for her “Song of the Lioness” and “The Protector of the Small” series. As the featured speaker at the event, the feisty and mischievous Pierce did not disappoint.
