Something evil has swept into the small western Maine town of Castle Rock on the heels of the latest winter storm. Sheriff Norris Ridgewick and his team are desperately searching for two missing girls, but time is running out to bring them home alive. In Washington D.C., thirty-seven-year-old Gwendy Peterson couldn't be more different from the self-conscious teenaged girl who once spent a summer running up Castle Rock's Suicide Stairs. That same summer, she was entrusted - or some might say cursed - with the extraordinary button box by Richard Farris, the mysterious stranger in the black suit.
