The novel Tú,la oscuridad by the Cuban-Puerto Rican writer Mayra Montero,based on an original"water"narrative,highlights the"hybrid"quality of Caribbean literature,which transcends geographical and cultural boundaries.The author completes her unique imagination and writing of Caribbean through the communication of various natural elements with the medium—water,which works as the primordial driving force;Then,through"The Law of Water",it not only illustrates the view of nature of the Afro-Caribbean community represented by Haiti,but also forms a resistance and deconstruction of the dominant Western discourse;Finally,the darkness of"water"intensifies the references and metaphors to"blackness",meanwhile,historical and political narratives are also inserted,so that the novel dissolves artistically the dichotomies between darkness and light,man and nature,the Western world and the Caribbean,etc.,embodying a universal ethical concern that transcends the limits of geography,race,class,and even species.
