Black Veil Protocol

When a disgraced Vatican cryptanalyst learns her dead sister is alive inside a covert intelligence cult that uses saints' relics to foresee and steer assassinations, she must infiltrate the order before the next prophecy targets the operative she should not want and the sister she never stopped mourning.

Elena Varela used to break sacred codes for the Vatican. Then her younger sister vanished after a fight Elena cannot take back, and the Church let Elena carry the shame alone.

Three years later, a murdered courier leaves Elena a relic case, a blood-marked cipher, and proof of the impossible: her sister is alive.

She is not being held.

She belongs to the Veil Protocol now - a clandestine network buried beneath charities, intelligence services, and old faith. Using relics taken from saints, the Protocol harvests visions of coming violence, then nudges the world toward the version of history it can survive. Presidents fall. Markets burn. Wars begin with a whisper in the right ear.

To reach her sister, Elena must let herself be drawn in by Adrian Rook, the Protocol's most lethal field operative - a man ordered to recruit her, watch her, and if necessary, kill her. But the deeper Elena goes, the more the visions sharpen around her, around Adrian, around a future soaked in blood.

Because the next prophecy is not a warning.

It is an invitation.
