Seven years after first contact, Providence Five launches. An enormous warship, built to protect humanity, it has a crew of four. Gilly, Talia, Anders, and Jackson will be confined to the ship for years, monitoring the AI-powered ship and reporting the war's progress to a global audience by way of social media.
