The Apothecary's Daughter, by Julie Klassen, from the Christian publisher Bethany House.
Book Description
Lillian Haswell, brilliant daughter of the local apothecary, yearns for more adventure and experience than life in her father's shop and their small village provides. She also longs to know the truth behind her mother's disappearance, which villagers whisper about but her father refuses to discuss. Opportunity comes when a distant aunt offers to educate her as a lady in London. Exposed to fashionable society and romance--as well as clues about her mother--Lilly is torn when she is summoned back to her ailing father's bedside. Women are forbidden to work as apothecaries, so to save the family legacy, Lilly will have to make it appear as if her father is still making all the diagnoses and decisions. But the suspicious eyes of a scholarly physician and a competing apothecary are upon her. As they vie for village prominence, three men also vie for Lilly's heart.
