When the fabled child is finally born to Velle’s reigning queen, the only citizen who does not rejoice is Elodie: the queen’s eldest daughter who has lost her claim to the crown. When her mother unexpectedly passes and her young sister takes the throne, Elodie’s future in Velle is threatened by a vindictive chaplain and a church wielding ultimate power. The only way to preserve her mother’s legacy is to retake the throne. To do so, she must eliminate the Third Daughter - her own sister. Desperate, Elodie slips away to the Midnight Market to purchase poison from an apothecary. Instead, she finds Sabine.
