The bodies pile up as the biggest hit horror series of the year concludes! Adeline is trying to keep the last few members of her family alive as her Crossed Mother brings an entire army of Crossed to attack their last fortress, an old hospital. Imagine, for a moment, the worst crimes against humanity. Picture the cruelest affronts to decency. Conjure your darkest nightmares... and then realize it could all be so much worse. When civilization crumbles in one terrifying moment; when people are gleefully breaking into unthinkable acts of violence all around you; when everyone you love has died screaming in agony: What do you do? There is no help. There is no hope. There is no escape. There are only the Crossed.
