Movement from one place to another lead to various changes in social and cultural practices. Diaspora is a mode of cultural production. Cultural identity is fluid, produced and reproduced so that it often results in hybrid forms of expressions. The issues dealt in diasporic literature are issues of identity, the problem of history, confrontations with racism, intergenerational conflicts, difficulties in building new supportive communities, alienation, and rootlessness. Diaspora is not merely a scattering or dispersion, but an experience determined by who travels, where, how and under what circumstance. Homelands, and even the lands of adoption, crop up between the imaginary and the real. The diasporic writers exemplify the disturbing shifting and enliven the past cultural heritage and tradition in their works. The novel Brick Lane (2003) by Monica Ali explores immigration, cultural shock and the problems involved in the movement from one country to another. The novel depicts the journey of Nazneen and Chanu from Dhaka to London. Nazneen migrates to London after her marriage with Chanu. Chanu is much older than Nazneen and is described as a man with “a face like a frog”. Chanu is working in London.
