The Legend of Diamond Lil: A J.J. Tully Mystery by Doreen Cronin
Kevin Cordell did the most excellent job of matching the illustrations with the story. (I've rarely seen a better match.) This book is only 144 pages in length and the lexile score is 630. What a great family read-aloud. You might want to read it to your younger friends or family members, Don't miss the first book in the series: The Trouble with Chickens. I'll keep you posted when a new one will be published.
