I Committed a One-Night Mistake with the Young Lady?

A contemporary woman finds herself reborn as an apprentice apothecary inside the pages of a novel where a saint is prophesied to overthrow a wicked noble. To her dismay, she is employed by the villain’s estate. There, she encounters a fragile, exquisite “young lady” rather than the dreaded antagonist. Resolving to shield and bring joy to this delicate soul, she remains unaware that the “lady” is, in truth, the very villain she fears—cleverly disguised.
