The House on Mango Street revolves around one girl and her struggle to fit the puzzle pieces of her identity – ethnicity, gender, cultural inheritance, sexuality, and economic status, to name a few examples – into a coherent whole. All of these facets come into play as Esperanza learns that, more than anything else, what defines her is her ability to tell stories. Her writing allows her to reconcile herself to those aspects of her background that made her feel uncomfortably different from her peers, and she emerges a confident writer with ambitious plans.
Though The House on Mango Street explores many facets of Esperanza's identity, the most central element of her identity is the role she adopts as a writer.
