Tensions run deep when Amy, Jack, and Carol realize they are trapped in the small conference room, an angry horde waiting just on the other side of the door. As they start to turn on each other, a small card is slipped under the door - a card catalog entry for an artifact the ancients called "a book". Is it some kind of warning? A threat? Soon more cards are pushed through, and the three friends realize that they are not going to get out alive, at least not unless they can find a way to appease the tens of thousands of angry books waiting for them just beyond the door.
