The Great Celestial War isn't coming. It's already here. After taking over the artificial metal planet from the enemy, Jace must focus his energies on locating Athena, the missing Cognitive and one of the greatest intelligence assets to ever exist. But Athena's whereabouts are entirely unknown. With no sign or clue to guide the search, Jace must continue to explore the many layers deep inside the planet, for they hold many secrets and technological wonders that reach far beyond what anyone can imagine. And somewhere deep inside the walls of this ancient place, someone is listening. An intelligence of unknown origins has been watching and waiting, spying on the humans. Their motives are unknown. Their identity is unknown. Their allegiance is unknown. But a Renegade never falters, and Jace has a job to do.
