The Magic Seeker: A Fairy Tale with Benefits. Sylvania, #6

Humans can't use magic. But he's cast a spell on her heart. Snowdrop has given up on ever using fairy magic. As the daughter of an ousted evil queen, she learned a dark version of magic that she refuses to use. Without magic, she's an outcast in the fairy community-unable to participate on a work crew and shunned by the others. Then a fairy elder offers to teach Snowdrop proper magic. If she can't learn from Larkspur, she'll never be able to learn.
She agrees, even though it means leaving home for the first time and traveling across the continent. Even though she'll have to travel with humans. One human, Arley, is more annoying than she ever could've imagined. He never stops talking. He never stops grinning. At least he stops flirting when she orders him to. (Ugh, she hates flirty men!) Amid all the talking, Arley lets her drive the horses. He asks about her past.
He teaches her to dance. And when his attention wavers, Snowdrop has to admit the embarrassing truth: she's fallen for Arley. The Magic Seeker has a loner heroine and a sunshiny hero in a low stress world that's perfect for fans of Wooing the Witch Queen by Stephanie Burgis. Each book in the Sylvania series can be read on its own but might contain spoilers for previous books. The Magic Seeker contains love scenes.
