The end was just the beginning . . .
Twenty-year-old Grace has a front-row seat to the end of the world after mysterious blackouts and a shock of bombings disrupt cities across the nation. What was once the perfect suburban life has become a daily fight to survive. All that was, now gone forever.
Determined, she prepares for what the future brings, armed with her sharp instincts, the desire to protect her loved ones, and her iron will to survive.
Just as Grace and her family begin to adjust to this new and uncertain environment, a terrifying threat emerges from within the darkness—a threat more petrifying than the apocalypse itself . . .
Told from two points in time leading up to one epic showdown, this twisty, suspenseful, and chilling account of a modern post-apocalyptic tale is a ride readers will never forget.
