The coalition was never supposed to survive long enough to matter.
Three factions. Ancient grievances sharp enough to draw blood. And a catastrophe already in motion.
When the Frequency Merchants trigger a cascade that threatens to bring multiple Resonance Pillars crashing down at once, Sera has no time left to negotiate trust - she can only demand it. Uniting the Echoborn, a faction of reformed Keepers still haunted by what they used to be, with the Unmade, beings the universe itself has tried to erase, and doing it while the cosmos unravels around them isn't diplomacy. It's a miracle that hasn't happened yet.
Every alliance has a price. Every compromise leaves someone behind. And the Dissonance spreading from failing Pillars doesn't distinguish between enemies and reluctant allies.
The Silence Protocol's most ambitious entry yet plunges deeper into the mythology that has captivated readers across seven books - delivering the coalition that changes everything, or destroys the last chance of saving it.
The reckoning you've been building toward is here. Don't miss it.
