The teenage girl, wrote de Beauvoir, is bound up in a “sense of secrecy,” a “grim solitude.” She is “convinced that she is not understood; her relations with herself are then only the more impassioned: she is intoxicated with her isolation, she feels herself different, superior, exceptional.” So it goes with a certain type of blockbuster YA heroine—the series protagonist who either doubles down on her sense of isolated exceptionalism, if she’s in a dystopian universe, or superficially attempts to reject it before acquiescing, if she’s in a romantic one.
