The one thing identical twins — quiet and bookish Abigail and globe-trotting event planner Charlie — can agree on is that this first Christmas without their mom will be difficult. When they unexpectedly get a last-minute chance to travel to Wales and spend a week running the Story Shoppe, an AirBnb/bookshop in Hay-on-Wye, they jump at the opportunity. Abigail is particularly excited, given the town’s role as the backdrop of the bestselling Winterton Chronicles, her all-time favorite Regency holiday romances.
