In the last years of the 20th century and the early years of the 21st, London Stone has made an increasing number of appearances in novels of imagination and fantasy. In Peter Ackroyd's novel "The House of Doctor Dee", the character Dr Dee, broadly based upon the historical figure of the occultist John Dee, claims that London Stone is the last remnant above ground of a glorious antediluvian and now buried city of London that he is searching for. London Stone appears as an embodiment of evil in Charlie Fletcher's trilogy for children "Stoneheart". It also features in "The Midnight Mayor", Kate Griffin's second Matthew Swift novel about urban magic in London, and in China Miéville's "Kraken", in which it is the beating heart of London and the sports shop that houses it hides the headquarters of the "Londonmancers" who may know the whereabouts of the Kraken stolen from the Natural History Museum. The third of a series of fantasy novels for children "The Nowhere Chronicles" by Sarah Pinborough, writing as Sarah Silverwood, is entitled "The London Stone": "The London Stone has been stolen and the Dark King rules the Nowhere..." In Marie Brennan's "Onyx Court" series, the Stone is part of the magical bond between the mortal Prince of the Stone and the fairie court beneath London. It is also mentioned in Nicci French's crime novel "Tuesday's Gone". The stone appears in several chapters of Edward Rutherfurd's novel, "London" (1997). In the second chapter we see it as the marker stone for all the roads in Roman Londinium, and also sitting beside the wall of the Governor's Palace as mentioned above as a hypothesis of its use or origin. It is seen again in the ninth chapter where the main family unit of the novel bring in the character of the foundling who is found propped up against it. The stone is one of the many central focus points in the novel that the author uses to tie the different time periods together. Ray Nelson's science fiction novel "Blake's Progress" (1975), based on the writings of William Blake, features an alternative history in which Cleopatra won the Battle of Actium and an Alexandrian Empire replaced the Roman Empire. In the alternate London, called Gogonooza, London Stone is still to be seen, standing in front of a Temple of Isis.
