Crown Slayer. Fallen Suns, #3

Final Galactic War Decides Humanity's Fate The Kyndred have returned. Not as saviors. Not as gods. As tyrants. They want their crown back-and they will burn the galaxy to reclaim it. Castor carries the only weapon that can stop them: the echo. But the echo demands a price. To wield it fully, he must become what they were-or destroy the very idea of power forever. The Anvil Pact and Enduring Compact have united against him.
The Forgotten are shattered. His crew is gone. He stands alone. But he has learned something the Kyndred never understood: power is not a crown to be inherited. It is a weapon to be wielded-and broken. The throne is waiting. The galaxy is dying. Castor doesn't want to sit on it. He wants to shatter it. Crowns are not inherited. They are shattered.
