A reclusive raccoon makes room in his life for new friends and new projects. In the furthest corner of a long-forgotten junkyard, Roscoe lives a life that suits him. But when a disaster sends three visitors to his gate looking for a new home, he finds that he can create more with others than he ever could on his own--and that together they can build an environment that's better for everyone. In each story in this series, the Tinkerers put on their engineering caps to come up with creative solutions to help others in their world. Along the way, they explore topics that align with Common Core and Next Generation Science Standards.
