Christine Garcia's The Aguero Sisters and Julia Alvarez's How the Garcia Girls Lost Their Accents are novels that revolve around the conflicts and tensions among the members of the two immigrant families, the Aguero sisters from Cuba and the Garcia sisters from the Dominican Republic, arising mainly from their need to come to terms with their ambiguous identities. This article focuses on the ways in which the Aguero and Garcia sisters through their hybrid identities overcome boundaries and exclusive categories so as to challenge homogenizing, hegemonic systems, and open vistas into new, non-essentialist modes of identity that still can be represented in their specific configurations.
