Children’s book author David Sargent Jr. came to Stilson Elementary School Tuesday to read several of his books to the kids, as well as introduce them to his canine companions, Emma and Spike. The dogs are the stars of his most recent books and were an instant hit with children, parents and staff that had assembled in the Stilson gym. He opened his visit to Stilson by reading one his books and then bringing out the central character Emma, a black and tan wire-haired chihuahua.
