Earth is under siege from monsters that rise from the deep and descend from the stars, and only an elite Special Forces unit stands between humanity and extinction. But when the entire team is wiped out by an unknown threat, a new commander in chief is forced to rebuild from nothing.

The replacements make no sense at first. Chosen by an enigmatic assistant, the new squad looks more like a pack of rebellious teenagers than the world’s last line of defence. But as the true scale of the coming danger is revealed, this unlikely team must grow into its burden, face the horror head on and prove that they may be humanity’s final hope against the darkness closing in.
