When a gunman is seen in the school, Adam and Zoe try to make it out alive.
It's like the entire school floods into the stairwell. People pound down the stairs toward us. Their voices clamor, frightened voices. They push and shove toward the blocked exit door, trying to escape the school. Like fish in a bucket, that's what we are. My mouth goes dry. A locked stairwell seems like a good place to kill a lot of people at one time. I grab Zoe's hand. "Come on. We have to go back up."
