Horrors haunt the Christmas season as life-drained bodies litter the countryside, each marked with a strange symbol. The Justice League responds–but it’s a trap! The heroes are pulled from our world, but not before Batman helps Robin escape. Now Damian Wayne must seek out Zatanna and the one and only Santa Claus if there’s any hope of saving their friends and family. Santa comes to the aid of the DCU heroes in the crossover-event sequel you wished for! And you must have been extra good because a wintry mix of DC’s wildest characters arrive this time to face a powerful foe…the Silent Knight!
