What is the moment, that exact moment when everything changes and the friends you have been become the lovers you might be? Soulmates from birth Karim and Raheen finish each other's sentences, speak in anagrams, and lie spine to spine as children. They are irrevocably bound to each other and to Karachi, Pakistan. It beats in their hearts - violent, polluted, corrupt, vibrant, brave, and ultimately, home. However, Raheen is fiercely loyal and naively blinkered and she resents Karim's need to map their city, his need to name its streets and to expand the privileged world they know.
