Her writing focuses on contemporary social issues. She is a perceptive observer of the changing urban milieu and her writing closely examines the contemporary Bengali middle class. Crisis in human relationships and the changing values of the present era along with degeneration of the moral fibre of the society in the backdrop of globalisation and consumerism are depicted in her prose. Exploitations and sufferings of women regardless of their social or economic identities find a distinct voice in her writing. While she is famous for her writing on women's issues, she does not consider herself as a feminist. She took up many odd jobs in her early youth and finally joined the public service which she left in 2004 to become a fulltime writer. Her long career is reflected in many of her stories and novels.
