In Surfacing, Margaret Atwood used the two kinds of theories such as, Colonialism and Post-colonialism, because the novel depicts on searching of their identity and a woman who returns to her hometown in Canada to find her missing father. Accompanied by her lover and another married couple, the unnamed protagonist meets her past in her childhood house, recalling events and feelings, while trying to find clues for her father's mysterious disappearance. Little by little, the past overtakes her and drives her into the realm of wildness and madness. Even though these kinds of things are happened in the novel that is why Surfacing called as a colonial and post-colonial novel. © Journal of Language and Literature.
