The quote reflects the intoxicating and overwhelming experience of a character in the novel "Blonde" by Joyce Carol Oates, where the feeling of a glass sliver in the heart signifies a mix of beauty and pain. The protagonist, fueled by Benzedrine and champagne, perceives every interaction as laden with significance, enhancing the emotional intensity of their life in Hollywood.

This highlights the seductive yet painful nature of fame and relationships within the entertainment industry. The mention of the Blond Actress suggests a naivety in her understanding of this world, as she begins to grapple with the harsh realities that others have already come to accept.
