Joining her archaeologist uncle at an ancient Peruvian temple, twelve-year-old Samantha explores its underground passages. Disappearing artifacts and stories of a haunting draw her into a mystery whose dangers grow more immediate when her older brother goes missing.

A routine excavation near Cambridge becomes dangerous when Samantha discovers evidence of Queen Boudicca’s fortress. With a theme-park development threatening the site, she must protect an important artifact and decide whom to trust among those invested in concealing her discovery.

Samantha joins her uncle’s excavation at Preah Vihear, financed by a film studio. Discovering that publicity tactics have inflamed a territorial dispute, she assembles allies to prevent the escalating violence from costing lives, destroying the site, and ruining her uncle’s career.
