CELESTE ASHBURY

Sovereign Protocol

The final battle lines are drawn. Allegiance is survival.

Extracted from the icy crucible of Iceland, the haunted but resolute quad—Liam, Eliza, Javier, and Noah—possesses the horrifying truth: Deputy Director Carmichael, Seraph, stands ready to unleash Sovereign Protocol, a global cyberweapon hidden within the Agency itself. Though exonerated in shadow, they reject a return to the compromised institution, choosing instead the perilous path of independence.

Their target: Agency HQ. The occasion: the International Security Summit. With the world's leaders gathered, Carmichael plans his final move, using the summit's impenetrable security as the perfect shield for activating his devastating protocol. For the team, it's a homecoming fraught with peril, a return to the lion's den where they were once hunted, now as infiltrators aiming at the heart of the conspiracy.

Operating from the shadows, they must execute an audacious, near-impossible plan: breach the fortress during its highest alert state, navigate layers of biometric security and elite guards, and rely on fragile, high-risk alliances with insiders—ghosts within the machine who gamble everything to help them. Liam must walk among former colleagues, a phantom in plain sight. Eliza must wage digital war against unbreachable systems. Javier must push his scarred body to its limits in the subterranean depths. Noah must coordinate the chaos, predicting Seraph's moves from an exposed position.

Failure is not an option. Sovereign Protocol's activation promises global chaos. Success demands flawless execution, unwavering trust, and perhaps the ultimate sacrifice. As Seraph becomes aware of the ghosts moving within his walls, the confrontation escalates, forcing unthinkable choices. Their unique bond, forged in love and tempered by betrayal, will be tested as never before. Can they dismantle the protocol and expose Seraph before the countdown ends? Can they all survive the return to the heart of darkness?

Sovereign Protocol delivers the explosive, heart-stopping conclusion to The Cipher Entanglement trilogy. Witness the final, desperate gamble where broken allegiances are settled, unimaginable costs are paid, and the fierce power of love and loyalty stands as the last defense against annihilation.
