Critical Mass (Old Mans Comeback #8)

A fragile alliance finally comes together, uniting factions that have every reason to distrust one another. With the Mahshi poised to strike, a rare advantage offers hope that the war might be ended before it consumes the galaxy. But a hidden threat moves faster than diplomacy, turning a precision operation into something far more dangerous—and far more costly.

As Flip and Sorsha confront a fanatical enemy willing to burn everything in its path, the price of survival becomes brutally clear. Revenge-driven forces collide with desperate choices, and not everyone will walk away. The coming battle may decide the fate of the universe—but long before the Mahshi are faced, the cost of victory is already being paid.
