What Became of Magic: A Novel by Paige Crutcher

Aline Weir, a witch who can talk to ghosts, has kept her talents hidden ever since a disastrous school slumber party, choosing to be invisible and use her powers in secret to help lost souls reunite with the keys to send them home. All the while, she finds solace in a bookstore and the three mysterious women who run it... until Aline discovers the book of Mischief, and her powers are enhanced. Living a solitary life until the age of thirty, Aline's life takes an unexpected turn when the wrong (or perhaps right) person witnesses her using her powers and she is invited to a town that doesn't exist on any map. Arriving in Matchstick, Aline learns of a lost magic that desperately needs to be found and only her unique powers can do it. But what she's not told is that Magic is a person. One that is dangerous and seductive and has been waiting for a witch with a power like hers for centuries.
