As the frenzy of the Christmas shopping season descends on the Swiss Miss, Lydia Troyer, an Amish girl on rumspringa who helps Cheryl in the shop, receives a cryptic text message from an unknown phone number: I know what happened to Mark Troyer. Lydia is shaken and explains that Mark is her cousin, a teenage boy who vanished three years ago. Some people said the talented young craftsman simply ran off, having been quite taken with the Englisch lifestyle. But Lydia is convinced Mark would never have left home without telling her good-bye. She and other family members worry that something bad happened to him. Now it seems like someone knows the secret behind his disappearance. Cheryl, with the help of Naomi Miller and her other Amish friends, is determined to get to the bottom of this mystery in time to brighten the Troyer family’s Christmas.
