O is for Outlaw is available as an audio book in both abridged and unabridged versions (on both tape and CD) read by Judy Kaye (Random House Audiobooks). Kaye, who has also read all of the preceding alphabet books on tape, has received much praise from fans as the voice of Millhone and Grafton states that she is "crazy about her" (http://www.barnesandnoble.com).
