For this book, best-selling children's author Mary Pope Osborne was inspired by a Fourth of July she spent in a small Pennsylvania town. Her warm account captures the joy of America's favorite summertime celebration. On the Fourth of July, a family joins the rest of their town in Memorial Park to celebrate America's Birthday. When the sun goes down, everyone sits on the grass for the concert. The band plays, then the fireworks start. Millions of lights fill the night sky with bright colors.
