Although the title of the book may make you think this is a paranormal romance, it is not.  There are three "fates" who serve to match the main characters and make them fall in love (they seem to be serving the needs of the heroine, but this is never explained) and also intervene at a critical point to ensure the HEA.  These are the only paranormal elements and they really struck me as lazy storytelling - they just make it so the author doesn't have to explain why a confirmed bachelor would suddenly marry a woman he's never met before (and one who is the opposite of his physical type) and ensure that the heroine is rescued.
