…what he has experienced is merely love’s painless presage, the expression without the soul. He wonders if it is a lack within himself. Is there a part of the brain from which love comes that in his case has drastically malfunctioned? The world is awash in love – on the radio, in movies, in the pages of novels. Romantic love is the common cultural narrative, yet he seems immune to it. Thus, though he has yet to taste the pain that comes with love, he has experienced pain of a different, related sort: the fear of facing a life without it.
Justin Cronin, The City of Mirrors
