}}
In Matthew Swift's London, just about anything is possible. As the Midnight Mayor, protector of the city, Matthew has incredible power and resources at his disposal. Not that he really wants them. In fact he'd rather not have all the hassle, if he's quite honest. But a new drug is swamping the streets of London - Fairy Dust. This deadly magical drug eventually turns its users into fairies, who then disintegrate into the dust that they've been taking, ready to be collected and sold again. And this perverse practise is not Matthew's only issue. Some teenage vandals have had their souls sucked out and social worker Nabeela wants the help of the Midnight Mayor to work out exactly how that happened. But the more Matthew digs into both issues, the more he starts to realise that the source of the problem may be closer than he initially thought.
