Spirits In The Wires by Charles de Lint

A contemporary urban fantasy set in a city where the intersection of music and technology awakens restless presences that live inside electronic networks; as strange, mischievous and sometimes dangerous spirits begin to leak through the wires, a young woman and her circle of friends—both human and otherworldly—must draw on folklore, creativity and community to confront the threat, heal personal and communal wounds, and reconcile modern life with older, hidden magics.
