When a deputy asks for help with a wedding proposal and a man connected to his future wife is found dead, Nora Pennington and her fellow readers investigate the connection to the woman's past and the secret she is hiding from everyone.

While January snow falls outside in Miracle Springs, North Carolina, Nora Pennington is encouraging customers to cozy up indoors with a good book. Even though the shop and her bibliotherapy sessions keep Nora busy during the day, her nights are a little too quiet—until Deputy Andrews pulls Nora into the sci-fi section and asks her to help him plan a wedding proposal. His bride-to-be, Hester, loves Little Women, and Nora sets to work arranging a special screening at the town’s new movie theater. But right before the deputy pops the question, Nora makes an unsettling discovery—someone has mutilated all her store’s copies of The Scarlet Letter, slicing angrily into the pages wherever Hester Prynne’s name is mentioned. The coincidence disturbs Nora, who’s one of the few in Miracle Springs who knows that Hester gave up a baby for adoption many years ago. Her family heaped shame on her, and Hester still feels so guilty that she hasn’t even told her future husband. But when a dead man is found on a hiking trail just outside town, carrying a rare book, the members of the Secret, Book, and Scone Society unearth a connection to Hester’s past. Someone is intent on bringing the past to light, and it’s not just Hester’s relationship at stake, but her life.
