ERIC AND SAVANNAH BURST THROUGH THE DOOR, BOTH YELLING their heads off. “Let’s go! Those guys are in the tunnel.” I wiped the tears out of my eyes and wheeled the chair around. They were a mess—sweaty and breathing hard, with long streaks of dirt marring the shimmery silver of their suits. Savannah’s hair was frizzing up around her head like a white-blond puffball, and where their faces weren’t flushed from exertion, they were covered in dust. “Wow!” Howard was right behind them. “Look at all these tapes.” He grabbed one labeled Space and Near-Planet Colonies. “Take it with you,” Eric said. “Take whatever you want.” He started filling his pockets with his own collection of videotapes and other records. “Nate’s trying to screw the grate back in,” Savannah said. “He thinks it might give us a little extra time.” I opened my mouth to speak, but no sound came out. I knew I should tell them what Fiona had said, what she’d threatened to do. I knew we should take a vote, just like we had with the guns.
