Blue is the color of Karachi, the city of lights, the rich and poor, the joyful and the desperate. It's the color of the oceans that surround the city, the shrines that hide the dreaming Sufi saints. Twenty-two year old Pakistani American Karim Asfar decides to jump on a plane and discover this city, in the country where his parents were born, yet a place to which he has no emotional ties. With the help of his rock-Sufi cousin Akbar, beautiful but conflicted colleague Nazli, and a beggar boy called Abdullah who haunts the shrines of the saints, Karim discovers there's much more to Karachi than political turmoil, religious extremism, and spicy food. Eager to make a difference, save Pakistan's endangered environment, and rescue Abdullah from his life of begging, Karim embarks on a search to discover his past and his future, while the Sufi saints deliver blessings and warnings to guide him on his way.

Encompassing religion, culture, identity, the immigrant's journey to the new world and back again to the old, this witty, moving novel comments on the influences that shape Pakistan and its people today. Modern-day Pakistan, a country struggling to find itself in the new century, provides the scenario for Karim to make choices about what - and who - he really wants to be in both the worlds he belongs to.
