Explore the wildly inventive, thrill-ride adventure set deep in the mysterious jungles of South America from New York Times bestselling author James Rollins
While on an expedition to Peru, archaeologist Dr. Henry Conklin makes several startling discoveries. High amid the snowcapped Andes a mysterious mummy is found hidden in a cave. And deep in the sweltering jungle below, the remains of an ancient Incan city are unearthed.
Nestled between two soaring peaks, this mysterious ancient territory called the Cloud Ruins has remained undisturbed for centuries, protected by ingenious traps that only the most clever and courageous dare to maneuver. But where the perilous journey inward ends--in the cold, shrouded heart of a breathtaking necropolis--something else is waiting for Conklin, his nephew Sam, and their exploratory party. A thing created by man, yet not human. Something powerful . . . something astonishing . . . something terrifying. And now their amazing adventure of discovery has been transformed into the ultimate challenge: survival.
