New stars appear overnight-silent, wrong, and moving with impossible precision. Astrophysicist Mina Kade sees the pattern first: an armada of colossal ships sliding into Earth's orbit like a new sky being installed.
Then the world goes dark in waves.
Satellites die. GPS collapses. Communications rot. Humanity fires its best weapons-and the armada learns from every shot. Military bases vanish with surgical cruelty. Command chains shatter. And when the ships finally open, the invaders descend: fifty-foot giants engineered for one purpose-clearing territory.
Cities become traps. Streets become kill zones. Survivors retreat underground, living by new laws of light, sound, and heat, hunted like rodents by a system that can steer air, flood tunnels, and paint districts for extermination. But Mina discovers something worse than the giants: a hidden coordination language-resonance-that binds ships and tools into one perfect machine.
So she fights back the only way she can: not with bullets, but with interference.
Alongside Tala, a ruthless migration leader; Kerris, a broken-smooth soldier who refuses to die obediently; Jun, a surface runner who learns to live in the enemy's shadow; and Calder, the fragile spine holding a terrified community together-Mina turns the invaders' own signal into a weapon. A disruptor. A song. A trap.
And when the sky itself begins to stutter, Mina uncovers the truth that changes the war:
Earth isn't the target.
It's the test bed.
