Welcome to the Empty Quarter, the domain of Djinn, ghouls, demons and the effrit who take the shapes of beasts. You used to walk among us, and we among you. Now things are different. Now we are Unseen. Alif is a half-Arab, half-Indian, 23-year-old hacker working in the Arab Emirates. His job is to provide security to enemies of the Arab states, ranging from pornographers to militant Islamists. Alif has fallen in love with the beguiling Intisar, an aristocratic woman he meets online. But their budding love affair is cruelly ended when her father arranges a marriage for her with a man of her class...A man who turns out to be the state's leading censor, a shadowy and powerful figure known only as 'the Hand'. As their final communication, Intisar sends the heartbroken Alif a mysterious old book. Bound in what looks like human skin, and titled The Thousand and One Days, Alif soon realizes that this token of affection is actually a dangerous source of old world magic. And as the keeper of this amulet - this Djinn-penned tome of secrets - Alif is about to become a wanted fugitive from both the corporeal and the celestial worlds...
