It wasn't supposed to be real, and it really wasn't supposed to be her. The President of the United States has vanished. Heather knows she must now lead America and the world, but everything she once believed in is changing. With no support, experience, or hope, Heather must decide between governing a divided nation or caring for her own broken family. America is not the only country affected; billions of people have suddenly disappeared, causing plane crashes, car accidents, and imminent war. During this crisis, some people seek truth while others seek power. Hospitals everywhere are overrun with victims, but one nurse, Emma Carpenter, has a plan, and nothing-not the vanishings, not her lying sister-will stop her.
