The battle for the fate of Earth has only begun as Detective Inspector Dave Barnes and his team must fight against a malevolent AI hell-bent on dominating multiple worlds.

With Terra, a counter-Earth in a parallel dimension, under its control, the tyrannical AI known as Oracle continues her relentless march across the multiverse‚ and now she holds Earth Prime in her sights.

While Dave Barnes and members of The Castle battle to stop the dangerous AI from succeeding in her invasion, all is not lost on Terra where a group of resistance fighters are marshalling their forces to free those who have been assimilated as mindless foot soldiers.

With conflict waging on both worlds, and Oracle tightening her grip, hope comes from an unlikely source when the duplicitous Colonel David Barnes offers information that could prove vital. But can this master of deception be trusted to aid in the fight for two worlds?

As Oracle becomes increasingly unhinged, and with the fate of humanity at stake, it becomes clear to those who resist that the AI will stop at nothing to rule the multiverse. In a desperate struggle to survive, can those on opposite sides unite in a mission to save two worlds? And, with the stakes so high, will all who fight live to see freedom from Oracle's reign of terror?
