Lucy King is only an hour away from embarking on the most incredible vacation of her life: White sandy beaches in a tropical paradise, snorkeling and sunbathing in peaceful tranquility. But as Lucy looks forward to her trip, a sinister plot is unfolding that will demolish the world as she knows it. An unknown bio-terrorist group unleashes a virus that virtually wipes out the earth’s population—leaving Lucy, and a small faction of survivors, trapped inside her high school to wait out the apocalypse. As war, looting, and death wreak havoc outside, inside, the students must contend with a tyrannical and paranoid principal and their own struggles of being orphaned, frightened, and unsure of what the future will bring. What begins as a basic fight for survival turns into a search for answers that will challenge everything Lucy has ever known about her life and her family.
