Djinn city : a novel / Saad Z. Hossain.

Indelbed is a lonely kid living in a crumbling mansion in the super dense, super chaotic third world capital Of Bangladesh. His father, Dr. Kaikobad, is the black sheep of their clan, the once illustrious Khan Rahman family. A drunken loutish widower, he refuses to allow Indelbed go to school, and the only thing Indelbed knows about his mother is the official cause of her early demise: "Death by Indelbed." But When Dr. Kaikobad falls into a supernatural coma, Indelbed and his older cousin, the wise-cracking slacker Rais, learn that Indelbed's dad was in fact a magician--and a trusted emissary to the Djinn (or genie) world. And the Djinns, as it turns out, are displeased. A "hunt" has been announced, and ten year-old Indelbed is the prey. Still reeling from the fact that genies actually exist, Indelbed finds himself on the run. Soon, the boys are at the center of a great Diinn controversy, one tied to the continuing fallout from an ancient war, with ramifications for the future of life as we know it.
