Starl Keep : Unbound Series

The government hunted him before he even knew why.

Leo was just a boy when his father became the most wanted man in the world — blamed for a virus that brought civilisation to its knees. That night, Leo lost everything. What he gained instead was a secret buried in his blood.

Years later, he survives in the ruins of Zone 16. Staying invisible. Staying alive. But the past has a way of clawing back to the surface — and something far older than the government, far darker than the undead, is already moving in the shadows.

Some secrets were never meant to stay buried.
