Hex Appeal by Jamie K. Schmidt

Sleeping with your boss is awkward. Discovering he’s your boss AFTER sleeping with him? That’s a hex-level disaster.

With hair that changes color with her moods and a passion for teaching defensive magic that actually works, Ceries has never been the model magical educator. But even she draws the line at accidentally seducing the principal.
After a night of cherry bomb cocktails, heated debates about magical theory, and the best sex of her life with a deliciously uptight wizard, Ceries arrives at her new teaching position at Grimm Mawr Academy to discover her one night stand is actually Principal Malachai Starcatcher—her new boss. Even worse? He’s adamantly opposed to her teaching the Bewildering Fog Hex, the very spell she believes could save students’ lives and the exact spell that once led to his greatest professional failure.

With matchmaking magical accessories pushing them together and a scheming trustee driving them apart, Ceries and Malachai must overcome their differences to protect their careers, their reputations, and the safety of every student at Grimm Mawr Academy.

Hex Appeal is when professional boundaries melt faster than a chocolate cauldron in July and the best magical theory debates end horizontally.
