Unnatural History is an original novel written by Jonathan Blum and Kate Orman and based on the long-running British science fiction television series Doctor Who. It features the Eighth Doctor, Sam, Fitz and Faction Paradox. Plot In London during the year 2002, the dark-haired Sam Jones is living a normal life, though struggling with a drug addiction, when the Eighth Doctor arrives in the shop she works in and tells her that she should have blonde hair and be travelling with him. Shocked by this, she runs out onto the street to get away from him and is attacked by a ten-year-old boy, who claims that she shouldn't exist. When the Doctor rescues her, she agrees to go with him to San Francisco. When they arrive, the Doctor finds Fitz and explains that when the TARDIS destroyed the Earth, but reversed time, a scar in space and time was left behind and strange creatures from other dimensions are being attracted to the city by it. The TARDIS has become trapped inside the scar, and will be crushed by the strain of trying to stabilise the scar in three days unless it is removed.

The Doctor's attempts to contact the Time Lords to obtain new equipment to close the scar fails, and he meets the boy again, who reveals that he is a member of Faction Paradox, but he claims that he isn't here to harm the Doctor, just to observe his actions. Later the Doctor notices a Kraken in the bay, which will destroy the city looking for food if it detects the energy coming from the scar, but the TARDIS is currently blocking it from detecting them. Now under another time limit, the Doctor finds a scientist called Joyce who promises to help repair the equipment needed to close the scar. The Doctor tells Sam that her biodata is vulnerable to change from the pulses coming from the scar. One of Fitz's contacts kidnaps them and delivers them to a man who fits them with tracking devices and releases them. In Golden Gate Park the Doctor discovers lines of his own biodata lying exposed on the ground, and seeing this removes the tracking devices.
