To save the human race from the ultimate cosmic threat, Jason will have to become something far beyond human.

New Toronto is a fractured city-arcology on a dying Earth, where hope is as scarce as clean air. For Jason, survival means scavenging the ruins beneath the city — where any day could be his last.

But everything changes when an ancient alien obelisk — the ABADDON BEACON — attacks Jason’s mind from afar, making his dormant psychic abilities spiral out of control. After barely surviving Abaddon’s psionic possession attempt, Jason and his companions are left with no choice but to find the obelisk before it consumes him.

Problem is, Abaddon has been sealed within a top-secret United Earth Federation research lab for over a century, silently worming its alien technologies into human society, presented as gifts with a far darker purpose. The Beacon doesn’t just speak; it infects, projecting its viral energies far beyond the walls of the lab.

And Jason isn’t the only one hearing Abaddon’s call. Across the Solar System, a ruthless Emperor will stop at nothing to seize the Beacon’s power for himself.

As the Imperial invasion of Earth looms, Jason’s quest to confront Abaddon will force him into a critical choice: master the strange power growing inside him … or succumb to the Beacon’s godlike influence, ushering in mankind’s doom.

The Call of Abaddon is a gripping mythological tale of humanity’s struggle to overcome an unimaginable darkness, blending the political intrigue of Dune with the eldritch terror of Lovecraft, and the explosive world-building of The Expanse.
