The novel “The Silent Stars Go By” by Dan Abnett was published for the first time in 2011.
The Eleventh Doctor promised Amy, and Rory to take them home for Christmas but mistakenly takes the Tardis to another planet, where the travelers find a great cold and a lot of snow. The Doctor and Amy venture into the area while Rory returns to the Tardis to get a heavier coat to wear.
The Doctor and Amy come across some inhabitants of the planet, who welcome them with puzzlement. The Doctor tries to use his psychic paper, but when it’s read even by an illiterate inhabitant, the others think that it’s some kind of conjure. Once out of the Tardis, Rory searches for his travel companions, but spots menacing creatures and flees. He runs into human natives in search of a missing local woman, but before he can try to explain that he doesn’t know anything, the group is attacked by the creatures.
