Othappu is a Malayalam novel written by Sarah Joseph and published in 2005. The novel is the last in the trilogy which includes 'Alaahayude Penmakkal' and 'Mattathi'. While 'Mattathi' is a kind of sequel to 'Alaahayude Penmakkal', 'Othappu' follows the pattern by having a central female character and protagonist. The novel deals with the decision of a nun to step outside the convent and embrace a life free from the shackles of established religious norms and practices. In this, the character 'Marghalitha', comes in logger heads with the church and society which refuse to accept her personal views and individual freedom and expect her to conform to the framework in place regarding those joining the nunnery. The English translation of the book named 'Othappu: The Scent of the Other Side' won the Crossword Book Award for translation.
