Sovereigns of Ruin — D.M. Pruden

In the scorched remains of a post-apocalyptic world, cybernetically enhanced veteran Monk stands at the edge of oblivion—his failing augmentations and haunted past propelling him into one last daring quest. When a mysterious force awakens ancient alien technology beneath the ruins of Knossos, his solitary existence is shattered, and his mission morphs into a desperate bid to control a power that could either redeem humanity or obliterate it entirely. With every step steeped in danger and betrayal, the stakes are monumental: Can one man's fight against cold, unyielding tyranny unearth a future worth saving?
