A keepsake, a remembrance, a celebration: USA TODAY’s Passages is a rich and touching look at the lives of those who left us in 2012 – ranging from pop’s troubled goddess to the reclusive first man on the moon, from a wise sheriff in mythical Mayberry to a brave schoolteacher who saved her students in Connecticut. These are the stories of more than 235 people who changed entertainment, science, sports, business and our world, leaving legacies large and small. Passages is a USA TODAY e-book worth turning to again and again.
