The Treehouse : Mark Victor Hansen Library : 9798885810708 : 04 Nov 2022 : An inspirational story about kids in middle school who learn how to develop skills, run a business and help their community at the same time.Darius and Katie's life did a complete turn-around one day when they discovered a pile of scrap lumber at a building site in their neighborhood. While carrying wood home on their bikes, they got help from a new friend, Joe. With the idea of having a place of their own, they built a treehouse. Using their extra materials, they fixed a neighbor's stairs. They started helping many others in their community with their "Handy Kids Carpentry". Despite opposition from a town official with a personal agenda, they prevailed and learned valuable lessons about building a business.
