Former academic Rimli Sengupta has chosen a subject close to her heart for her debut book in English. It\u2019s the story of Buttermilk, a maid in Kolkata, whose life is a rollercoaster ride that straddles her village where she has her marital home, the city where she works, and the suburban slum where she lives. The author brings to light the story of invisible people who work in our homes through the tale of her own maid, Buttermilk. There\u2019s a line in the book that may resonate with many readers: \u201cSimply put, Buttermilk makes my life possible. For this, I pay her a monthly salary that just about covers dinner for two at a nice restaurant.\u201d It\u2019s a snide at the way society treats domestic helps even as this unorganised class works hard to keep our homes running like clockwork. The life of Buttermilk\u2014spanning five decades, first as Karno\u2019s daughter and later as Jhoro\u2019s wife\u2014is worth reading about. We travel along with her through her different life stages, as a daughter to the strong-willed Karno, a wife to the dimwit Jhoro, a not-so-submissive daughter-in-law, and later a strict mother-in-law to Rupa. The free spirit of Buttermilk, along with her dogged determination, help her fight every battle, be it getting an Aadhar card issued from her village after umpteen attempts or the endless fight in getting a land lease in her family\u2019s name. Karno\u2019s Daughter is a work of non-fiction, which, told in the voices of the author and protagonist, reads as a narrative that\u2019s both engaging and heartwarming. The events that unfold, beginning with the abject poverty in which Buttermilk is raised, to her crawling up the social ladder where she owns a piece of land and a pukka house, are grim reminders of the exploitative lives most maids live. Karno\u2019s Daughter is an easy book to read\u2014the sentences are framed well, the chapters move quickly and there\u2019s no exaggeration of basic human suffering. It\u2019s a narrative that will leave you nodding your head in agreement and even, at times, tear you up. It\u2019s a glimpse into the world of never-ending struggle.
