When the nuclear war comes, Evelyn learns the cruelest lesson of all: her husband Shane chooses his pregnant first love over her, taking away her seat in the rescue vehicle and leaving her to die from radiation. Then fate turns back the clock. Three years earlier, Evelyn wakes with everything she needs to strike first—Shane’s fortune, a hidden underground fortress, thousands of children saved, and a full plan for doomsday, while the ones who betrayed her are left to answer for it.
