An irreverent, tragicomic, astoundingly articulate memoir about going blind—and growing up On his eighteenth birthday, Ryan Knighton was diagnosed with retinitis pigmentosa, a congenital, progressive disease marked by night-blindness, tunnel vision, and, eventually, total blindness. In this penetrating, nervy memoir, which ricochets between meditation and black comedy, Knighton tells the story of his fifteen-year descent into blindness while incidentally revealing the world of the sighted in all its phenomenal peculiarity. Stumbling literally and emotionally into darkness, into love, and into adulthood, he uses his disability to provide a window into the human condition. His experience of blindness offers unexpected perspectives on sight and the other senses, culture, identity, language, and our fears and fantasies.
