Gr 4-7--Smart kids score again in Trenton Lee Stewart's third adventure (Little, Brown, 2009) about the Mysterious Benedict Society. This time, Reynie, Kate, Stickie, and precocious Constance are in protective custody in Mr. Benedict's house to keep them from falling into the hands of the nefarious Mr. Curtain who is determined to steal back the Whisperer machine and control the minds of the people of Stonetown and the world. When a blackout thrusts the town into darkness and Constance goes missing, the Society puts their heads together to thwart Curtain, recover Constance, and save the day. As in the previous two books, Stewart fills his story with poems, riddles, and puzzles that will delight listeners, and he never shies away from intelligent vocabulary. Del Roy returns as narrator and permeates the tale with his rough, gravelly voice. Elegant writing and charming narration fuse to give the feeling of an old, treasured classic. A fine entry in an enjoyable series.--Tricia Melgaard, Centennial Middle School, Broken Arrow, OK[Page 58]. Copyright 2008 Reed Business Information.
