Pretty Damned Things by Holly Wade Matter

Fortune is an itinerant musician without a past who braids memories into her hair. Maud is a sheltered small-town girl and an unwitting heir to the notorious McBride family magic. The two young women meet when Fortune is commissioned to bring Maud to a rich man whose grandson she cursed. United by their love of music and their hunger for the road, Fortune and Maud form a friendship ... one that is threatened not only by Fortune’s mission but by their mutual desire for a man called Lightning.
