In the wake of their mother’s mysterious death, Linno and Anju Vallara are raised in Kerala by their father and grandmother. When seventeen-year-old Anju wins a scholarship to study in New York, she jumps at the chance to embrace all that America has to offer, but in so doing commits an act of betrayal that severs her relationship with her sister.

When Anju’s lies catch up with her, she runs away, helped by a kindly stranger who somehow knows things about Anju’s past. Meanwhile, Linno has begun a journey of her own: towards her sister, towards the memory of their mother, and towards a future she could never have imagined.

Atlas of Unknowns is an unforgettable tale of two sisters whose bonds are powerfully tested, and the secret histories and hilarious eccentricities of families everywhere.
