As per the author:
The world of Faerie has always been with us. The fairy tales, ballads, and folklore of the mortal world are only shadows of the true, sometimes terrible reality of the fae. They thrive on secrecy, survive on secrecy, and keep their Courts in the shadowed places where the light doesn’t fall, existing in constant parallel to the world we know. They aren’t human. They don’t want to be. But sometimes they take human lovers, and sometimes, those unions are fertile ones. Changelings aren’t stolen children; they’re the mortal halfbreeds born where the fae and human worlds collide, never able to fully belong to either, outsiders from birth.
