Zack Eon thought his battle with destiny was over. After using the alien watch to stop the Sun Harvesters from terraforming Earth, he'd finally returned to a normal life. But peace doesn't last. The King of Nightmares—once a boy twisted by telepathic powers—has returned. Resurrected in the body of an unborn child, he now seeks to unleash his terror once more.

With time on his side, Zack must dive back into the labyrinth of time, facing relentless cycles of death and resurrection. Each step backward reveals new horrors, pushing Zack to the limits of his power—and his sanity. As he races to prevent collateral damage and save the world, Zack faces an even greater question: how far can one go to change fate?

In this gripping third installment of the 13utterfly series, the stakes are higher, the nightmares darker, and the fight against destiny never more urgent. Will Zack find a way to stop the King of Nightmares without losing himself in the process?

Time is running out, and the future is more uncertain than ever.
