Yet here she stands—ankle-deep in ferns older than civilization, staring at a horizon that defies known geography—following coordinates etched into a relic no modern instrument can date. She isn't alone. A ruthless rival expedition has reached the valley first, and they have no intention of sharing its secrets. With the greatest geographical find in history at stake, Lena must decide what matters more: truth or preservation.
