Some secrets don't die with the person who kept them. Seventeen-year-old Mia Calloway has spent three years grieving
a father she thought she knew. James Calloway was a librarian.
Quiet. Steady. Safe. Then a USB drive arrives in the mail -
postmarked Zurich, addressed in his handwriting - and everything
a father she thought she knew. James Calloway was a librarian.
Quiet. Steady. Safe. Then a USB drive arrives in the mail -
postmarked Zurich, addressed in his handwriting - and everything
Mia believed about her life begins to unravel. Her father was never a librarian. He was a spy. And before he
disappeared, he spent two years assembling the one thing that
could stop a catastrophic cyberattack capable of collapsing the
entire Western financial system. He left it for Mia. Because she
is the only one he trusted. And because she is the only one
clever enough to finish what he started. Now Mia is running. From shadow agencies. From a traitor buried
deep inside the intelligence world. From a four-minute window
that stands between civilisation and collapse. Armed with nothing
but a dead man's encrypted files, a retired spy handler, and a
mind sharp enough to crack codes that professionals couldn't
touch, she has to do the impossible - and bring her father home. THE CIPHER PROTOCOL is a breathless YA thriller that blends
espionage, mystery, and the unbreakable bond between a father
and daughter. Perfect for fans of fast-paced spy fiction,
high-stakes adventure, and stories where the sharpest weapon
in the room is a teenager who refuses to give up. A story of secrets, shadows, and the courage to follow the
truth - no matter where it leads.
