The Witch With an Itch by Virginia Nelson

Flemming Fletch is a witch with the perfect life—until she gets hit by a moving truck full of her own belongings lovingly packed by her suddenly-ex-fiancé. She heads back to her hometown to figure out where it all went wrong, but instead of solving problems, she makes even more.
One badly cast love spell later, and she’s covered in hives. She can’t ask other witches for help—forbidden spells come with some nasty punishments, after all—so she turns to a healer. Can a guy dedicated to healing bodies possibly cure her broken heart?
