Just in time for vacation, Boxcar fans can dive into summer reading with three warm-weather adventures about the Aldens, together in one volume. In The Mystery at the Ball Park, the baseball season is in jeopardy when someone steals a special bat and Jessie's glove. Then the team almost doesn't make it to their first game In The Mystery of the Hidden Beach, the Aldens try to find the terrible secret that the beach holds. And in The Summer Camp Mystery, the children investigate why someone is sabotaging the annual Olympic competition at Camp Seagull. Boxcar Children Mysteries, always just right for summer reading, are now three times better with the The Boxcar Children Summer Special.
