`When little Kusumom woke up that day on the Mala Arayan hill of Erumapra, the old Eruma Pããrãã, she never had any idea that that day would change her life, forever. Unknown to her, she was standing on the same courtyard where a few generations back, her ancestor, the occult priest of the Lord Ayyappan of Sabarimala had conducted his affairs. Baker had converted these hills to Christianity, including her family. She could see the Erumapra Church below. Her mother was nowhere to be seen and she goes in search of her, only to see her mother in a compromising position with the vicar of the church, at the stream where the family once had their sacred grove. She from then on, became the custodian of a secret, a secret that had the potential to destroy the moral fabric of her neo-Christian village and the very existence of her family. Eruma Pããrãã is a simple story of a girl from the Mala Arayan tribal hills of Kerala, who had a past to carry and a present, which she had to endure till she takes the bold step to shake her off her past, ready to face the future on her own. The novel also narrates the myths and folklores about the Mala Arayan hills around Erumapra, issue of caste in the Christian churches and also a different narration of the conversions done by the European missionaries around these hills.
