Officer Mike, on traffic patrol! Situation? Under control! 'When people need help, we rock and roll!' With Kersten Hamilton's high-energy rhyming text that begs to be read aloud, and R. W. Alley's warm and silly illustrations, this picture book is a fun and reassuring way to tell kids about what police offi - cers do. 'With a well-crafted text spiced with sound effects, this appealing picture book is highly recommended.' , starred review for
