The sky is their ocean.
Flight is life.
And nothing on Valkren has ever fallen without reason.
Until the day it does.
On a world where islands drift and skywhales sing through endless blue, Rowen Thrace has always believed the sky was sacred-predictable, alive, and untouchable.
Beautiful.
Peaceful.
Perfect.
Until it goes silent.
When a skywhale is torn from the clouds by something no one can see, Rowen and her reckless best friend Cassian are the only ones who witness it.
No storm.
No wreckage.
No explanation.
Just a shadow in the mist.
Something ancient.
Something patient.
Something that has awakened.
As entire sky routes collapse into dead zones and more creatures vanish without a trace, whispers of an old legend begin to surface-of a world-ending predator that once descended from the second moon... and of a war that was never truly won.
Buried beneath classified military archives lies a truth no one is willing to face:
This isn't the first time the sky has been hunted.
And it may be the last.
Now hunted by the very people meant to protect their world, Rowen and Cassian are forced into a race against extinction-to find a lost battleship built to fight something no one fully understands.
Because whatever is moving through the sky isn't just feeding.
It's learning.
And when it's done-
There will be nowhere left to fly.
