Darkened Demigod by Shawn Phillips
Imprisoned miles below the surface of the post-apocalyptic Earth he crafted, the first and last modern-day demigod must come to terms with his failings that led to global annihilation. From the charcoaled ashes of remorse and uncontrollable anger must rise the embodiment of what he was meant to be—a savior for all humankind. However, who he is saving them from and why propels this demigod on a pained journey beyond his home planet, where he must face much more than just an advanced offshoot of humanity. He and the diminutive Bookworm will fight for Earth, but at a cost even a demigod will not be able to rectify.
