Jack loves staying at his dad's house. They have tacos and milkshakes, and make each other laugh. But lately Jack wonders if his dad is lonely when he isn't there. Then Jimmy arrives. Jimmy is loud and obnoxious, but Dad thinks he's clever and funny. Jack does not think he's clever or funny. And he's starting to wonder if Dad likes Jimmy better than he likes Jack. This beautifully written and illustrated book about the unconditional love a parent has for a child is both heartwarming and reassuring.
