After a terrifically hard and terribly disappointing day before the Fourth of July, Peanut Johnson, wandering aimlessly down Main Street, stumbles upon The Capital Z, a This and That Shop. Stepping inside, he meets Mr. Aloysious Zip, the kind and eccentric shopkeeper, who introduces Peanut to a most wondrous place. There are toys and trinkets, model cars and miniature wagon trains, even memorabilia from days gone by reminders, says Mr. Zip with an air of mystery.
Discovering everything from A to Z inside The Capital Z, Peanut also finds history unfolding before his very eyes. Touching a Kentucky rifle hanging on the shop wall, he is transported to the wilderness where he sees his Great-Great-Great-Great Uncle Milkweed Johnson fighting in Andrew Jackson's regiment during the War of 1812. George Washington's sword brings Peanut onto the battlefield where the General, on horseback, dodges bullet after bullet. And while staring at a beautiful stained-glass window depicting the building of the Tower of Babel, Peanut finds himself in a crowd of angry and confused spectators, all speaking different languages
But Peanut's visit to The Capital Z turns out to be much more than a journey through history. As he peers into the past with his Uncle Milkweed and some of America's greatest leaders, he finds courage and hope to face his own mistakes, taking his first steps from boyhood to those of a young man."
