The Lost Apothecary was immediately available on audiobook from the library and so I grabbed it. I don’t think I have read Sarah Penner before. This was a good back and forth in time story and nice audiobook. “Hidden in the depths of 18th-century London, a secret apothecary shop caters to an unusual kind of clientele. Women across the city whisper of a mysterious figure named Nella who sells well-disguised poisons to use against the oppressive men in their lives. But the apothecary’s fate is jeopardized when her newest patron, a precocious 12-year-old, makes a fatal mistake, sparking a string of consequences that echo through the centuries. Meanwhile in present-day London, aspiring historian Caroline Parcewell spends her tenth wedding anniversary alone, running from her own demons. When she stumbles upon a clue to the unsolved apothecary murders that haunted London 200 years ago, her life collides with the apothecary’s in a stunning twist of fate – and not everyone will survive.” (Amazon) I enjoyed this story very much and highly recommend it, especially on audio.
