Iggy has one passion: building. His parents are proud of his fabulous creations, though they’re sometimes surprised by his materials—who could forget the tower he built of dirty diapers? When his second-grade teacher declares her dislike of architecture, Iggy faces a challenge. He loves building too much to give it up! With Andrea Beaty’s irresistible rhyming text and David Roberts’s puckish illustrations, this book will charm creative kids everywhere, and amuse their sometimes bewildered parents.
