Eva Evergreen is determined to earn the rank of Adept Witch before she turns thirteen years old. If she doesn't, she'll lose her magic forever. For most young witches and wizards, it's a simple enough test. When she lands on the tranquil coastal town of Auteri, the residents expect a powerful witch, not a semi-magical girl. So Eva comes up with a plan: set up a magical repair shop to aid Auteri and prove she's worthy. She may have more blood than magic, but her "semi-magical fixes" repair the lives of the townspeople in ways they never could have imagined. Only, Eva's bit of magic may not be enough when the biggest magical storm in history threatens the town she's grown to love. Eva must conjure up all of the magic, bravery, and cleverness she can muster or Auteri and her dreams of becoming a witch will wash away with the storm.
