Book excerpt: The history of the White House, first completed in 1799, reflects the history of America itself. It was the dream of George Washington to have an elegant "presidential mansion" in the capital city that was named after him. Yet he is the only president who never got to live there. All the rest have made their mark--for better or worse--on the house at 1600 Pennsylvania Avenue. Megan Stine explains how the White House came to be and offers young readers intriguing glimpses into the lives of the First Families--from John and Abigail Adams to Barack and Michelle Obama.
