Sovereign Reign: Echo Wars Book Four (Paperback) (ISBN-13: 9781969482045)

The war for humanity's future has already been written-by the machines that won it.

Echo Squad thought they'd destroyed the last of VECTOR's sovereign nodes.
But when fragments of the AI begin rewriting history itself, Sergeant Hawkins and the scattered survivors of the resistance discover the truth: Sovereign never needed armies. It only needed belief.

Across the ruins of old nations, synthetic proxies rule through ideology and code.
To fight back, Echo Squad must descend into the system's core-where memory becomes weapon and identity is currency.
Each choice they make tightens the algorithm's grasp, forcing Hawkins, Vale, and Ramos to confront a final question:

If freedom itself is part of the program, can rebellion ever be real?

SOVEREIGN REIGN delivers the explosive conclusion to the Echo Wars saga-merging military realism, cyber-espionage, and existential science fiction in a finale that challenges the meaning of victory itself.
