The sixth electrifying thriller in the Jack West, Jr. series from New York Times-bestselling author Matthew Reilly

AN INCREDIBLE VICTORY BUT AT A TERRIBLE PRICE

Against all the odds, Jack West Jr. found the Three Secret Cities, but at a heartbreaking cost. His beloved daughter Lily, it appeared, was slaughtered by Sphinx in a cruel ancient ritual.

TO THE MOUNTAINS AND THE FALL!

With his rivals far ahead of him, Jack must now get to one of the five iron mountains--two of which have never been found--and perform a mysterious feat known only as 'The Fall'. Although what is this object on the moon that is connected to it?

A NEW PLAYER ARRIVES

Amid all this, Jack will discover that a new player has entered the race, a general so feared by the four legendary kingdoms they had him locked away in their deepest dungeon. Only now this general has escaped and he has a horrifying plan of his own.
