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.

It took one week to demolish the world and obliterate the earth’s population. And it took two weeks to solidify friendships and build-up a small society of survivors who must rely solely on each other to navigate the future’s unknown terrain. As Grant Trotter and Lucy King make their journey to Brixton, Nebraska in search of answers, the Oregon contingent of survivors must deal with Ethan’s failing health and some resentful, mysterious newcomers. Each group faces new challenges as they adjust to their new terrifying realities.

In the final book of the Virulent Trilogy… Ethan is now at home in the System. Teddy has been placed in the King’s care. The move to the Islands is looming. And Lucy and Grant are falling in love amidst the backdrop of anxiousness and pain. There are whispers of dissent among the survivors, and even Huck Truman’s cherished Elektos Board is starting to challenge his thirst for complete control. Back in Oregon, Dean and Darla begin the journey to Nebraska to find their children. But will they be too late?
