Book excerpt: When it comes to the environment, a community must work together. Cora is excited to enter the local sandcastle-building contest—until the contest is canceled due to litter at the beach. Determined to help save their favorite place, Cora and Mama get to work picking up the single-use plastics that have washed onto the shore. It will take more than four hands to clean up the beach, but Cora is just getting started.
