Who will survive when the future can only be saved by the past?

A vicious insomnia pandemic devolves into a devastating apocalypse, and humanity teeters on the brink of extinction in the thrilling final installment of the Percivious Trilogy, Escape.

Emerging from the dark side of the moon, the HELIX and its crew embark on a desperate effort to save the last of their species-and ours.

An unexpected alliance forms between humans and the XYZ-Earth's first intelligent hominid species-to stop the pandemic once and for all. But when unforeseen forces surface, Herriden, captain of the HELIX-which carries the last of the cetacean XYZs-must make an unfathomable choice, if it's not already too late . . .

Percivious: Escape is an astonishing conclusion to the Percivious Trilogy, in which life as we know it will never be the same.
