The Peacekeepers. The Citadel. Book 6.

In the Guadalupe Mountains of Texas, the peacekeepers discover the base for Phoenix Rising, which was a secret government project that planned to utilize the work of the development team who’d designed the Peacekeeper. The project plans called for storing one hundred fighters in the subterranean base. Those fighters would provide air cover for America in the event of a nuclear conflict. The fighters had not been delivered prior to the night of the quakes.

Inside that base, which the peacekeepers had code named the citadel, they discovered an aircraft unlike any other they had ever seen. Though the aircraft utilized peacekeeper technology, it was unarmed. In the wake of the retrofitting of the ship, Pol asked the question, “What upcoming event or challenge will make the resources of this ship and the citadel necessary?”

The peacekeepers learned the answer to that question just hours later.

Calling on all of their resources, the peacekeepers race to prevent a nuclear strike on American soil.
