The Goddess's Gift by Sarah Uzzle:
 
In a cottage by the forests, a quiet healer named Winna lives a cozy life with her two cats. With fruits from the forest to supplement her little farm’s crops and wild herbs to make healing salves, the mage has everything she needs. As Winna heals friends and neighbors with her weak magical abilities, she whispers grateful prayers to a nameless goddess who gifted the now-fading powers to her ancestors.

When the sweet healer takes in an injured cat, he proves to be far more than she bargained for. Because Lear is no ordinary cat, but a fey soldier in disguise, and he’s about to turn her calm life upside down.

Sparks soon fly between the humble healer and the flirtatious fey soldier, and more fey folk come out of the woodwork, revealing a world that Winna never dreamed she’d be a part of.
