When an Old Order Amish woman takes a job at a small-town pharmacy struggling to survive in a world of "big box" stores, her motive is to help her Plain community. But the advent of the holiday season brings an unusual mystery to the surface--and possibly love.

Twenty-four-year-old Holly Zook lives a unique life for a young Amish woman. Years ago, her bishop allowed her to continue her education and become the lead technician for Greene's Pharmacy, an old-timey drugstore that looks out for the Amish community--a group largely without secure healthcare plans. She knows she can't marry and hold onto her professional job. She's Amish, and she can only have one or the other, so she spurns love and works toward addressing treatable diseases--like the one that claimed her father's life.

As long as Holly continues to avoid Joshua Smucker, the one man who draws her like a warm hearth in winter, she should be fine. When something unexpected threatens Greene's Pharmacy, Holly and Joshua must work together to unravel what's happened and find the "missing" patient before the Board of Pharmacy shuts them down. As the snows of December arrive, with Christmas in the air, will Holly succumb to the generous spirit of the season?
