A Burst of Gray: A Novel in 100-Word Stories, Paperback/Ran Walker

Imagine a world where the only people who see in color are those who have found their true soulmates. Slate is a 40-year-old guy who, like billions of others, has only seen the world through its various hues of black, white, and gray. This wouldn't be a problem, except his parents were true soulmates and, therefore, Chromats (those who can see in color). As a result, he holds out hope for the unlikeliest of events. When, through a freak occurrence, he accidentally encounters his soulmate, Slate quickly discovers that his world will be irrevocably upended in ways he could have never imagined.
