Growing up in Calcutta, born just 15 months apart, Subhash and Udayan Mitra are inseparable brothers, one often mistaken for the other. But they are also opposites, with gravely different futures ahead of them. It is the 1960s, and Udayan--charismatic and impulsive--finds himself drawn to the Naxalite movement, a rebellion waged to eradicate inequity and poverty: he will give everything, risk all, for what he believes. Subhash, the dutiful son, does not share his brother's political passion; he leaves home to pursue a life of scientific research in a quiet, coastal corner of America. But when Subhash learns what happened to his brother in the lowland outside their family's home, he comes back to India, hoping to pick up the pieces of a shattered family, and to heal the wounds Udayan left behind--including those seared in the heart of his brother's wife.
