Strange Familiars by Keshe Chow

Two scholars of magical veterinary science must put aside their lust and loathing to save the world in the first installment of this whimsical, romantic, dark academia duology.

All Gwendolynne Chan needs is to get through final year at Seamere College, where she is on track to graduate as number one —as long as the pretentious prat Harrisford Briggs doesn’t beat her to it.
Harrisford Briggs’s father, the chief financial officer of Magecorp, a major global distributor of magic, expects him to come top of the class. Harrisford, though, can’t help but notice that his father has been acting odd. And there are strange whisperings, too, of uncontrollable surges of excess magic.
When these magical surges begin to rock London, causing chaos and explosions and animal familiars going feral, Gwen and Harrisford find themselves reluctantly involved, putting both of their veterinary careers at risk.

Along with Gwen’s snarky cat familiar, Gwen and Harrisford must team up to diagnose the problem. But as the two academic rivals fight their burgeoning feelings, they quickly realize that magic is not the only thing surging.
