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.

In London during the year 2002, 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.

The Doctor finds a scientist called Joyce who promises to help repair the equipment needed to close 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.

The Doctor learns that the man's name is Griffin, and traps him, who explains that his ambition is to categorize every creature in the universe.

After learning that Fitz has been kidnapped, the Doctor confronts Griffin, who explains that he wants to see the Kraken destroy the city.
