Parents need to know that several violent events are referred to, though not in detail, including the story of when Maggie's dad shatters his leg on duty as a firefighter. More significant is a scene recalling an incident during the Korean War when innocent civilians -- including children -- are shot while hiding underneath a bridge. Neither account is graphic, but Park does mention in the Author's Note that the bridge tragedy is "loosely" based on something that happened during the actual war.
Violence:Maggie's dad injures his leg during a firefighting accident; innocent Korean civilians (including children) are shot to death under a bridge during the Korean War.
Super For Readers--Even If They Are Not Baseball Fans
Baseball, especially the Dodgers, is featured in this book about a girl in the 1950’s. It is historical fiction because the baseball details are from actual games and because it involves facts about the Korean War. The information about the after-effects of war may be something a parent would want to discuss with the student.
