One Admiral lost in the void. Another leading a desperate defense. The Commonwealth is on the brink.

When the Fifth Fleet enters system J5934, they are outnumbered two-to-one by a combined force of Federation and Republic dreadnoughts. Admiral Saint John Powell watches from his flagship, the heavy cruiser HMS Providence, as the enemy obliterates his fleet and shears his ship in two, leaving him and forty-nine survivors drifting in a shattered hull with no drives, no sensors, and limited air.

While Saint John fights for survival in the deep dark of space, Admiral Perseverance Andrews refuses to accept the reports of his death. But there is no time for grief. The enemy has launched a final, crushing offensive targeting the Lincoln shipyard—the heart of the Commonwealth’s military production. If Lincoln falls, the “wolves are loose in the sheepfold,” and the path to every other shipyard and the capital itself will be wide open.

With the professional navy stretched to its breaking point, the Commonwealth must gamble everything on the new Ottawa-class dreadnoughts. These massive ships are unfinished and crewed by raw recruits, but they are the only tools left to blunt the enemy’s advance.

From harrowing hit-and-run strikes in hyperspace to massive artillery duels between dreadnoughts, The Resolve of the Commonwealth is a breakneck tale of military grit and tactical brilliance. Perseverance and Saint John must risk their lives—and their future together—to secure an unconditional surrender and end the war once and for all.

Perfect for fans of David Weber and Jack Campbell, this third installment of the Perseverance Andrews Series delivers hard-hitting fleet combat and high-stakes galactic drama.

Fans of starship combat, strategic warfare, and compelling leadership will be captivated by this thrilling tale.
