Beatrice Sims can hardly wait to join the Dirty Diggers at a summer camp for teen girls interested in unearthing the secrets of ancient ruins. Beatrice dreams of finding mysteries from the past while she yearns to make new friends. Instead, the WWII refugee from England is seen as an outsider by the other girls and when a precious artifact goes missing, Beatrice is suspected of being the thief. Yet when a violent storm threatens the camp, Beatrice discovers something even more valuable - the courage to face danger and compassion to help others.
