Seven years after first contact, Providence Five launches. It is an enormous and deadly warship, built to protect humanity from its greatest ever threat. On board is a crew of just four--tasked with monitoring the ship and reporting the war's progress to a mesmerized global audience by way of social media.

But while pursuing the enemy across space, Gilly, Talia, Anders, and Jackson confront the unthinkable: their communications are cut, their ship decreasingly trustworthy and effective. To survive, they must win a fight that is suddenly and terrifyingly real.
