Oleander girl - Chitra Banerjee Divakaruni

Although she was orphaned at birth, Korobi Roy has enjoyed a privileged childhood with her adoring grandparents, spending her first seventeen years in a beautiful, crumbling old mansion in Kolkata, India. But she is troubled by the silence that surrounds her parents' mysterious death and clings fiercely to her only inheritance from them: the love note she discovered, years ago, hidden in her mother's book of poetry. Just when she believes she has found true love herself, she discovers a devastating family secret that impels her on a courageous search across America, transforming her in ways she cannot imagine and facing her with the most difficult choice of her life.
