Barbarian Alien

Twelve humans are left stranded on a wintry alien planet. I'm one of them. Yay, me.
In order to survive, we have to take on a symbiont that wants to rewire our bodies to live in this brutal place. I like to call it a cootie. And my cootie's a jerk, because it also thinks I'm the mate to the biggest, surliest alien of the group.
Contains mature themes.
