J. K. Rowling is the best thing that has happened to children's literature since Lewis Carroll, Robert Louis Stevenson, Louisa May Alcott and Frank Baum. And she has finished up the Harry Potter series in fine form. After beginning to lose her way as her books got longer-- No. 6 was veering toward the leaden -- No. 7 is as good as it gets. We meet many of our old friends, the adventure rattles right along, and all is revealed in the end.
Thank you, Ms. Rowling.
