After being shot down in the middle of a war zone, five Thunderan warriors are fighting for their lives. Together they face a horde of heavily armored soldiers, and the team's only hope is to somehow break through their lines to reach the wreckage of their ship.

But even if Pumyra, Lynx-0, Shen, Ligon, and their hammer-wielding commander Bengali make it out alive, will they still be able to complete their mission? And even more important: who is the mysterious antagonist who is hunting them and what is his connection to the Book of Omens?
