Echoes of War by Daniel Gibbs, Fight the Good Fight

In a future where humanity stands on the brink of galactic conflict, one naval officer must rise to face overwhelming odds, defend freedom, and lead in the fight against tyranny. set in a far-future galaxy where humanity has spread to the stars. The story centers on the Terran Coalition, a democratic interstellar alliance under pressure both from within (politics, corruption, war fatigue) and from without (theocratic enemies determined to destroy them).
The Terran Coalition’s primary adversary is the League of Sol, a theocratic, authoritarian power ruled by the Ministry of Truth and a fanatical ideology that sees themselves as the rightful rulers of humanity. Conflict between the two sides is inevitable and total — the League wants to purge and dominate, while the Coalition fights to preserve freedom.
