Melvin might?

Bold Jack Truck and Payloader Pete encourage Cement Mixer Melvin and Rescue Rita to follow them rolling down a steep hill onto an incomplete bridge ramp and flying across a pit to the other side. Melvin just watches them and shivers, too scared to try, but when Rita, an ambulance, falls into the pit, though, he finds the courage to make the leap to help his friend. Possibly the first cement truck to wear glasses, Melvin makes a sympathetic main character for worried preschoolers, who can overlook the cartoonlike unreality of the action scenes. The copyright page notes that the illustrations were digitally drawn by Juan Pablo Navas and colored by Isabel Nadal and were apparently based on characters and environments developed by David Shannon, Loren Long, and David Gordon. The personified vehicles will appeal to truck-loving tots, though their parents may be less enthusiastic about reading, much less rereading, the story. For libraries with avid Trucktown fans.--Phelan, Carolyn Copyright 2008 Booklist

PreS-K-"Cement Mixer Melvin worries" is the opening line and central theme of this simple, predictable, and yet entirely engaging picture book. Melvin is such a worrier that he even worries that he might get worried. Just being with him makes others become worried. When Payloader Pete shows him and Rescue Rita an unfinished bridge, Melvin quakes with apprehension as other gutsy vehicles fearlessly roar and soar across the open expanse. Melvin believes himself incapable of such feats, and his fear of failure paralyzes him until he sees that Rita is in danger and needs his help. Only after he realizes the extremity of her situation does Melvin find the courage to act, and, with stunning foldout pages, he saves the day. The pages feature exuberant and adorably anthropomorphized automobile characters that are digitally and stunningly rendered in nearly overwhelming color that reflects the style of the "design team," especially the highly appealing art of David Shannon. This book is sure to be a hit with car-loving kids and will certainly resonate with worryworts.-Piper Nyman, Brookmeade Elementary School, Nashville, TN (c) Copyright 2010.
