In Operation OVERLORD, the stunning conclusion to the Event Group trilogy that began with The Beast and continued with Legacy of the Moon, it is time for humanity to go to war. The million-year plan is finally ready for what is always coming - Armageddon. Finally, the first step is taken and the assassinations begin, eliminating leadership and consolidating military control of the seas and airspace of the world's most powerful powers. Only one element in the world's arsenal can give Earth a chance to survive - a tiny alien creature that once saved the world in the Arizona desert, now it is called upon to outsmart its former masters. The only organization on the planet that refuses to accept the inevitable defeat of humanity, the Event group, is suffering from loss of personnel, torn apart by internal conflict. The group also faces a threat that may be far more dangerous to Earth's survival than attacks from deep space - their old enemies have returned for vengeance, and Department 5656's worst fears are realized - a security breach allows attackers to gain access to secrets inside the Nevada complex . War continues, countries fall, nations fight to the last man, and the fate of the planet depends on a few good men and women in this gripping fantasy adventure thriller from New York Times bestselling author David Golemon.
