For readers in the 9-12-year-old zone, what could be better than a new book by double Newbery winner Lois Lowry (鈥淣umber the Stars鈥 and 鈥淭he Giver鈥)? In Bless This Mouse (Houghton Mifflin, 160 pp.), Lowry (along with Caldecott winning illustrator Eric Rohmann) tells the story of Hildegarde, an oh-so-correct church mouse who must save her 鈥減eople鈥 from their worst fear (鈥渢he Great X鈥) even as a pushy rival tries to grab her place as lead mouse. Lowry has created a gentle page-turner, with a sweet cluster of characters at its core.
