Having described a father and a mother in previous outings, Browne now moves on to the pleasures of having a male sibling. The brother in question is “really cool,” from his hair to his ears, his clothes to his shoes. His many admirable skills include jumping, climbing, playing soccer, skateboarding and running so quickly he flies. He reads, writes and draws prolifically, blows bubbles, whistles, sings, dances and even “stands up to bullies and sits down on monsters.” Not to be diminished, the younger narrator realizes that he himself is pretty cool as well. Browne’s signature style is present in full force, and readers will enjoy the sly humor, cheerful hyperbole and attention to detail in the stylized illustrations. Labels explaining the coolest attributes are present in many of the pictures, and contemporary language will draw readers in. A suspiciously familiar gorilla casts an occasional appearance, which will delight fans both old and new. Overall, this straightforward tribute to brothers is energetic, heartwarming and a pleasure to read. Perhaps a book about sisters is not far behind. (Picture book. 3-6)
