Doctor Who: Tales of Trenzalore by Justin Richards

This anthology has four stories from the seige of Trenzalore and they range from an attack by the Ice Warriors to a foe that uses bones from a dead man to make his move on the small town of Christmas. The Doctor fights all four and wins but at a price each time because the people of Christmas don't always tell him what is going on on the outskirts of the town. This anthology is a must for any Doctor Who fan who want's to read what happened during the events of the episode the Time of the Doctor.
