Sheriff Colton Graves prefers the quiet life in Raven's Rest, Alaska, a remote town accessible only by tunnel and home to a hardy mix of locals and secrets buried in the ice. But when a camel wanders down Main Street—its head grotesquely sprouting a dozen eyes—Colton knows his quiet days are over. The bizarre incident leads him to NovaGen, a nearby research facility constructed inside a Cold War bunker, buried in the mountains above town. There, a trail of blood and eerie silence hints at something far more sinister than an escaped animal experiment.

In the icy darkness of the Arctic Ocean, a violent showdown between ruthless whale hunters and fervent environmentalists ends in explosive catastrophe: both ships sinking into the frigid abyss.

There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.
