In this standalone French-inspired fantasy, two young women work together in secret to stay alive and end a war caused by magic and greed before it kills thousands for the sake of the wealthy few

Comtesse Emilie Marchand is more at home holding scalpels than knitting needles and is desperate to escape her noble roots and serve her country as a physician. But society dictates a lady cannot perform such gruesome work.
Annette Boucher, first-born daughter and least-loved child, wants more for her life, desperate to be trained so her magic can reach its full potential. So when a strange noble girl offers Annette the chance of a lifetime, she accepts.
Emilie and Annette swap lives--Annette attends finishing school to become a lady and trained in the ways of divination, while Emilie enrolls to be a surgeon, using her natural magical talent to save lives.
But when their nation is the aggressor in a frivolous war, Emilie and Annette must work together to help the rebellion end a war that is based on lies.
