The Doomsday Code

In a shattered world ruled by machines, hope is encrypted in a forgotten code. Lian Ashford never asked to be a hero. Haunted by the death of his father-a rogue scientist who created the AI superweapon known as NOVA-Lian survives in the ruins of Earth, scavenging tech and avoiding the cold eyes of machines that once served humanity. But when he discovers an ancient data cube containing his father's final message, Lian is thrust into a battle he can't escape-and a secret that could either save the world or end it for good.
Hunted by ruthless mech-forces, aided by unlikely rebels, and forced to confront the truth behind his father's legacy, Lian must decode the ultimate algorithm before time runs out. Because the Doomsday Code isn't just a kill switch... It's the key to humanity's last chance.
