Years after the disappearance of most of humanity, Mark travels a blasted desert wasteland in the hopes of surviving to the next day. Then, his routine is shattered when he stumbles upon Horan, an exiled prince of a race of superpowered immortals called Primoi. Now with a golden opportunity to turn his own life around, Mark decides to ferry Horan across three continents to try and stop his power-mad uncle from wreaking untold havoc across what remains of the world.
