Rex clamps a hand on my arm and hauls me back just before I start bounding down the stairs. “Not that way!” he calls after me. “They’ll start checking the building at the bottom and work their way up. But there’s an elevator in the back that you can only access from up here. If you can fight your way to it, you can get out that way.” I nod and let him wheel me around and half drag me up the stairs to the fifth floor. Judging by the door we’ve come to, which is painted bright red and is made from some kind of heavy, extra-reinforced steel, we’ve reached the part of the building that they really really want to keep people out of. With a grunt, Rex yanks it open and we step inside. The ceilings are just as high up here, but there aren’t any inner walls. Instead it’s just one big room, crowded with computer stations around the edges and a massive topographical map of the East Coast in the center of the room. This is obviously the command center. “Quick, hide!” I whisper, and duck behind a computer station.
