The Summer of Riley — Eve Bunting

William's new dog, Riley, is in trouble. He chased a neighbor's horse, and local law punishes any animal that chases livestock. William will do anything to save his dog's life. Riley has become the friend he's
needed after his grandfather's sudden death and his parents' separation.

Will William and his friend Grace be able to save Riley -- even if several citizens and the bully Ellis Porter think Riley deserves the most severe punishment possible?
