Book excerpt: A rainy day gets Bill Collins thinking, "What the Gang needs is a tree house!" So with Poetry's family's old lawn umbrella and some elaborate thatch work, the boys create their own headquarters down by the river. Soon they discover that someone's living in their tree house! And when their guests turns out to be an African American man, prejudice rears it's ugly head within the Gang. Join the Sugar Creek Gang as they learn that the value of people has nothing to do with their skin color.
