K-Gr 2--These additions to the series deliver character-education lessons about being responsible and dependable. In the first story, Mighty Mike finds "sweet little Daisy" on the ground after she falls off a broken slide ladder. He looks around, sees that the whole playground in disrepair, and devotes an entire weekend to fixing all of the equipment. He is so tired that he sleeps through the luncheon held for him in appreciation of his work. In the second book, the heavy-equipment operator uses his smarts to diagnose a broken-down bus in the middle of a rainstorm. Naming engine parts and maintaining a cheerful attitude throughout the trying experience (Mighty Mike doesn't want to go back in the rain after a long day working in the gooey mud), he demonstrates his reliability. Each book offers some "What Would Mighty Mike Do?" questions for discussion. The bright illustrations and subject matter will probably create some fans for this hero, but the didactic delivery of the texts will turn off many children. Additional purchases where character-education books are in demand.--Amy Commers, South St. Paul Public Library, MN[Page 90]. (c) Copyright 2010.
