The novel “The Forgotten Army” by Brian Minchin was published for the first time in 2010.

The Eleventh Doctor takes Amy Pond to New York just when a Polar Woolly Mammoth found perfectly preserved is about to be presented in a museum. In front of a crowd, what’s supposed to be an animal that’s been dead for several millennia suddenly comes to life and begins to cause panic inside the Natural History Museum.

The Doctor manages to jump on the mammoth and control its movements as if it were a horse, temporarily taking it to a zoo. It seems that some American authorities are the biggest problem for the Doctor, but the situation changes when the mammoth’s true nature is revealed and together with it the real danger.
