Permitted Victories: A Military Sci-Fi Time Travel Thriller. The Abandoned Hours Trilogy, #2

The war was supposed to be turning in humanity's favor. Then the enemy started asking questions. Captain Adeya Koss is the only person in the galaxy who remembers hours that no longer exist. As the fleet's sole operator of the revolutionary Mk II reversion system, she can reclaim lost time, undo disasters, and save lives-but every erased hour remains with her alone. Every victory leaves a scar that only she can see.
When a groundbreaking six-hour test expands the machine's reach beyond anything previously thought possible, Koss discovers that the true cost of rewriting time may be far greater than anyone imagined. The dead return. Lost moments vanish from history. Yet the memories remain, accumulating in the mind of the woman tasked with carrying them. Meanwhile, along the contested Carthen Approaches, the enigmatic Veil have changed their tactics.
Instead of attacking, they watch. They probe. They stage strange encounters and withdraw. Fleet commanders see hesitation. Koss sees something far more dangerous. The enemy is studying her. Across light-years of contested space, an invisible contest unfolds between two minds separated by species, culture, and time itself. Every battle becomes a message. Every decision becomes a clue. As impossible patterns emerge from years of war, Koss begins to suspect that the Veil possess a secret that could rewrite everything humanity believes about the conflict-and about the nature of causality itself.
But with each use of the Mk II, the burden grows heavier. The line between remembered and forgotten begins to blur. The machine's power is increasing. So is the price of carrying its history. And somewhere beyond the frontier, an enemy intelligence may already know her next move. As fleets gather and the future of the war hangs in the balance, Koss must decide whether humanity's greatest weapon is also its greatest vulnerability.
Because some victories come with a cost that time itself cannot erase. Permitted Victories is the thrilling second installment of an epic military science fiction trilogy, blending fleet warfare, first-contact mystery, temporal intrigue, and unforgettable characters into a sweeping tale of sacrifice, memory, and the hidden price of changing history.
