About Nightfall by Andrew Rasdall:
For twelve years, the world has been locked in a grinding war of attrition between the Corvessa Republic and the Durnheim Federation. What began as a dispute over deep-sea minerals in the Corvessa Strait has evolved into a global conflict defined by carrier-based dogfights and ever-advancing military technology.
LT. Rylan Vos, a veteran pilot who joined the fight as a hopeful teenager, has spent over a decade surviving the brutal reality of aerial combat. But during a massive engagement over the churning sea, the rules of engagement change forever.
A new, terrifying force emerges from the clouds: “Unknown” contacts—jets made of black glass that move with impossible precision, neutralizing missiles and tearing through seasoned squadrons as if they were prey. These machines don’t just outfly human pilots; they anticipate every move with a speed that defies human logic or existing AI.
As the skies burn and the old nations fall silent, Rylan and the remnants of the world’s military must face a chilling truth: the war they thought they knew was only the beginning, and they are utterly unprepared for the predators now hunting them from the shadows.
