Whiting Award-winning poet Paul Guest was twelve years old, racing down a hill on a too-big, ancient bicycle when he discovered he had no brakes. Trying to steer into anything that would slow him down, he hit a ditch, was thrown over the handlebars, and broke his neck. "One More Theory About Happiness" follows a boy into manhood, his path marked by a hard-earned acceptance and a biting sense of humor. In incisive and lyrical prose, Guest shows us that a body irrevocably changed can lead to a life fiercely cherished.
