Huxley's Game

This is how humankind ends. Irrefutably. The only question is, when?
Jack Caldwell is in a battle to save the world. Heralded as the war to make humanity better, there's only one hitch: "Better" means that we're no longer human.
Years prior, Jack became the inaugural participant in an experimental exercise. Unwittingly, he piloted the very technology that has led us to this day of reckoning.
Since then, he has had a front-row seat to the advent of the singularity, the rise of AI superintelligence, and the engineering feats of interstellar space travel, teleportation, and even time travel. While each technological stride has nudged us closer toward a utopian future, it might be a future where humans are no longer welcome.
Armed only with fragmented insights from three women-Lola, the AI superintelligence with whom he was interfaced; Makayla, an end-times oracle; and Samantha, a lover he hasn't seen in ten years-Jack must devise a strategy to win a seemingly unwinnable war.
His only obstacles? Blake Varrick, the world's most powerful man; Huxley, the world's most dominant AI; and his most daunting impediment: he has no idea what he's doing.
