We've all missed the chance to say something important. Friends fall out of touch, loved ones pass away, or sometimes the courage required is simply lacking — and thank-yous, regrets, feelings, and secrets are left unshared. In 2009, Jackie Hooper came up with a way to help people recapture a moment that had once passed them by — she began asking them to write letters.

Based on the popular blog The Things You Would Have Said, this extraordinary collection of letters brings together the moving, surprising, and inspiring stories of ordinary people. By turns heartwarming, funny, sad, and wise, the letters showcase a remarkable range of voices and subjects. From the indignant young boy urging his bully to become "a better man," to the woman apologizing to the girl she picked on in high school, to a man thanking the woman who protected his family from Nazis, the letters bring together an outpouring of emotion that is as compelling as it is cathartic.
