A new digital-only ebook from BBC Books, tells four dramatic tales from the Eleventh Doctor’s last stand - defending the town of Christmas for 900 years against a horde of monsters.

As it had been foretold, the armies of the Universe gathered at Trenzalore. Only one thing stood between the planet and destruction – the Doctor. For nine hundred years, he defended the planet, and the tiny town of Christmas, against the forces that would destroy it. He never knew how long he could keep the peace. He never knew what creatures would emerge from the snowy night to threaten him next. He knew only that at the end he would die on Trenzalore.
