Publisher's Weekly Review

The plot of Caldecott Medalist Wiesner's latest gives his artistic gifts a new challenge: rendering machines as living beings. A robot family welcomes an assemble-it-yourself baby robot but can't get it running properly until their daughter comes to the rescue with her trusty toolkit. Shapely architectural lines form the metallic family--willowy mother Diode, stout father Lugnut, small daughter Cathode, chubby baby Flange, and dog Sprocket--and an illuminated floor lights the family from below, giving the spreads a warm glow. Energy tightens as the adults try to build the malfunctioning robobaby ("Thanks, Cathy," says Diode, screwdriver in hand, "but this is a mother's job"). Relatives come to visit ("Aunt Gasket!"), and robotechs arrive to snag the rocket-propelled baby with a net ("He needs a complete overhaul"). As the chaos intensifies, trying to work out which parts belong to which robot becomes its own visual puzzle. Against the how-things-work mayhem, smooth fields of color, streamlined panel artwork, and fastidious speech bubble typography make every spread elegant. Ages 4--7. (Sept.)
