The Geographer's Map to Romance (Love's Academic) by Holton

Geography professors in a failed marriage of convenience inconveniently reconnect for an emergency mission in this swoony historical-fantasy rom-com.

Professor Elodie Tarrant is an expert in magic disasters. Nothing fazes her—except her own personal disaster, that is: Professor Gabriel Tarrant, the grumpy, unfriendly man she married for convenience a year ago, whom she secretly loves.

Gabriel is also an expert in magic disasters. And nothing fazes him either—except the walking, talking tornado that is his wife. They’ve been estranged since shortly after their wedding day, but that hasn’t stopped him from stoically pining for her.

When magic erupts in a small Welsh village, threatening catastrophe for the rest of England, Elodie and Gabriel are accidentally both assigned to the case. With the fate of the country in their hands, they must come together as a team in the face of perilous conditions like explosions, domesticated goats, and only one bed. But this is easier said than done. After all, there's no navigational guide for the geography of the heart.
