When a British space probe is intercepted by a sinister alien vessel on the eve of Christmas, it marks the beginning of an audacious invasion of the Earth by the Sycorax—and the just-regenerated Doctor is not fit for service. Will Rose be able to save the world from this nightmare before Christmas—or see it destroyed? A new novelization of the Tenth Doctor's first adventure, read by Camille Coduri (Jackie Tyler). Unabridged.
