The widespread social malaise that pervades Earth's people is initially indicated by a bizarre physical phenomenon: people begin to lose their shadows. The idea of the separation of person from shadow is far from new (J. M. Barrie, for example, used it in Peter Pan more than a century ago). Shepherd, however, effectively pairs it with another, more profoundly disturbing change: the loss of memory.

Profound disorientation results as people literally do not know where to turn. Concepts such as home or family become meaningless as no one knows where they belong. This widespread phenomenon becomes known as the Forgetting, and all over the planet only a handful of people escape:

The ones left all started forgetting too, and disappeared. Wandered right out of their houses and couldn't remember how to get back, or died of starvation in one room, unable to figure out how to unlock a door or that there was an upstairs, until the doors themselves vanished from the walls and the stairs flattened to hallways, trapping them forever. . . . Who would have thought that you'd need a shadow to work a key or recall your mother's name?

This concept then begs the question: Which memories are the most essential, and which are the most precious? Shepherd encourages the reader to think about what means the most to them and what constitutes survival. Those who do remember live in such terror of the Forgetting that they compulsively document their actions and thoughts in case they or their loved ones need to refer to them later.
