Claire owns the Croissant-toi, but while her days are filled with pastries and customers, her nights are dedicated to stealing exocores. These new red gems are heralded as the energy of the future, but she knows the truth: they are made of witches’ souls.
When her twin—a powerful witch and prime exocore material—disappears, Claire redoubles in her efforts to investigate. She keeps running into Adèle, however, and whether or not she can save her sister might depend on their conflicted, unstable, but deepening relationship.
