Other Waters by Eleni Gage. The book is being released by St. Martin's Press on February 14, 2012.
Amazon says this about the book: Maya is an accomplished psychiatry resident with a terrific boyfriend, loving family, and bustling New York social life. When her grandmother dies in India, a family squabble over property results in a curse that drifts across continents and threatens Maya's life. Or so her father says-- Maya (being a modern woman, an American, and a doctor) doesn't believe in curses, Brahman, or otherwise. But when her father suffers a heart attack, her sister miscarries, and her career and relationship both start to falter, Maya starts to worry. A trip back to India with her best friend Heidi, Maya reasons, will be just what's needed to remove the curse, save her family, and to put her own life back in order. Thus begins a journey into Maya's parallel world-- an India filled with loving and annoying relatives, vivid colors, and superstitious customs--a cross-cultural, transcontinental search to for a chance to find real love.
