Summer nights at Pine Cone Girl Scout Camp hold more adventure than Judy Grant and her Beaver Patrol expected. When the girls discover a ghostly cottage overlooking the dunes and stumble into a network of secret caves, what begins as an innocent camping trip becomes a real mystery. Smugglers operate in the darkness along Singing Sands, and the ghost stories the older campers tell might be more than folklore. Wirt captures that universal childhood feeling of summer nights stretching into possibility, where ordinary campers become heroes. She writes with warmth and trusts her young readers with genuine stakes - real danger wrapped in the safety of friendship and courage. The book endures because it understands exactly what children want from summer: freedom, friends, and a mystery worth solving.
