Chitra Banerjee Divakaruni - Sister Of My Heart

Anju is the daughter of an upper-caste Calcutta family of distinction. Sudha is the daughter of the black sheep of that same family. Sudha is startlingly beautiful; Anju is not. Despite these differences, since the day the two girls were born—the same day their fathers died, mysteriously and violently—Sudha and Anju have been sisters of the heart. Bonded in ways even their mothers cannot comprehend, the two girls grow into womanhood as if their fates, as well as their hearts, are merged.
When Sudha learns a dark family secret, that connection is threatened. For the first time in their lives, the girls know what it is to feel suspicion and distrust—Sudha, because she feels a new shame that she cannot share with Anju; and Anju, because she discovers the seductive power of her sister’s beauty, a power Sudha herself is incapable of controlling. When, due to a change in family fortune, the girls are urged into arranged marriages, their lives take opposite turns. One travels to America, and one remains in India; both have lives of secrets. When tragedy strikes both of them, however, they discover that, despite distance and marriage, they must turn to each other once again.

A real good novel with authentic characters and a very interesting storyline. In my opinion this is the best book of Chitra Banerjee Divakaruni I have ever read.
But the author should have ended the wonderful story after this first book. The ending was kind of open, but it was a good and realistic ending although.
