'It all starts when Bronny and her backpacker friends decide to break into a vacant townhouse in London. During the day they work as cleaners, pool attendants and bartenders; at night they take lots of drugs and have sex. The house becomes the centre of their world, and, for a while, Bronny is happier than she ever thought possible. Then the banging noises begin... And what Bronny doesn't realise is that the basement isn't empty.' (From the publisher's website.)
