Siege

THE WEAPON IS AWAKE. Deep beneath the burning sands of the Sahara, a forbidden archaeological dig goes terribly wrong. A massive underground explosion reveals something impossible: a buried metallic fortress the size of a city, older than human civilization. It wasn't built to protect us. It was built to cleanse us. THE DOME IS EXPANDING. Within hours of the discovery, an impenetrable energy field erupts from the sand.
It is growing, swallowing villages, military bases, and mountains. Anything it touches is disintegrated at a molecular level. If it reaches the Mediterranean Sea, the resulting atmospheric collapse will trigger a global extinction event. THE TEAM IS EXPENDABLE. With the world's governments paralyzed by fear, a covert agency assembles a suicide squad to do the impossible: breach the fortress and kill the machine from the inside.
Kane Mukiza: An elite Rwandan Special Forces captain who knows how to survive where armies fail. Amara Khalid: A disgraced Egyptian military engineer who understands the ancient code better than the people who found it. Miller: A rogue pilot with a stolen dropship and a death wish. THE WAR HAS BEGUN. Inside the dome, physics is broken. Gravity shifts, walls move, and the ancient guardians of the city-lethal, insect-like machines-have woken up.
But they aren't the only threat. A ruthless warlord has already breached the core, and he intends to use the weapon to redraw the map of the world in fire and blood. This is not a rescue mission. It is an assassination. The target is a machine god, and the clock is ticking.
