Grimjack the Bone Picker has never really cared for Christmas, but with the recent attack by the Stridian Armada weakening the horde, he has no choice but to go to Santa Claus for help. He arrives at the North Pole, only to find that he can't deliver the Christmas wish given to him by the Bejeweled Alliance because Santa has disappeared! So he reluctantly teams up with a group of unlikely heroes to try to save Christmas before the Torrelians can harness the grief of a year without presents and end the horde.

Will Grimjack learn the true meaning of Christmas, or will he become steadfast because of the truth hidden behind all the gifts and decorations?
