Witchful Thinking (Elemental Love, 1) by Celestine Martin

Love is the trickiest spell of all.
 
Lucinda Caraway loves living in Freya Grove, the mystic seaside town where charms, hexes, and magical beings of all kinds are the norm. She spends her days teaching high school history and her nights reading tea leaves and tending to her conjure garden. It’s a good life . . . but she can’t stop wishing for more.

Until one night, that wish turns into a spell, and suddenly Lucy can’t say no. Not to a public karaoke performance. Not to running a 10K. And, most alarmingly, not to her high school crush, Alexander Dwyer, who needs her help unjinxing his new house—which just happens to be right across the street from hers.

Alex has spent the last ten years traveling the world on adventures Lucy has only ever dreamed of, and he’s planning to leave again as soon as his house is safe to sell. But until Lucy can unhex herself, she and Alex are stuck together. And with so much magic in the air, maybe the next spell Lucy casts will be the one that convinces him to stay.
