Some superheroes wear rocket-propelled boots, drive super-powered cars, and have X-ray vision. But other superheroes wear army boots, drive tanks, and go away for long trips to make the world a safer place. It's a tough job, but that's what superheroes have to do. With Melinda Hardin's simple text and with Bryan Langdo's endearing watercolor-and-pencil illustrations, Hero Dad makes a difficult and tender subject more accessible to children with parents serving far from home.
