A 500-year-old artifact and a DVD revealed clues that Jack and Maya's parents were murdered on an expedition to find a fabled key with supernatural powers. So much for the tragic accident, a lie they'd been fed. The teens jet off to Peru to retrace their parents' journey, unaware that they were walking into a trap. The only way to catch the killer was to find the key. With an encrypted map from a shaman, they explored an ancient civilization and uncovered a hidden crypt that was heavily guarded by a century's old secret-society. Little did they know that the crypt would be just the beginning of their mission. Their quest turned deadly when a shape-shifter threatened to stop them. Could she be the girl that was flirting with Jack? She was always around. The siblings had only four days to decipher clues, survive booby-traps and fend off wicked spirits. Would using primeval mystical ceremonies that raise the dead be enough to stay at least one step ahead of the treasure hunter that was stalking their every move? Was he the one that murdered their parents? Can they uncover the mysteries of the secret prophecy and find the key first?
