We open fire. It doesn’t matter that we don’t have the best aim. The Mogadorians are basically sitting ducks. With all the shooting coming from the walls, they’re starting to panic. Many of them are knocked down to their knees by the turrets or the medicine balls, at which point Sarah and I pick them off. Some make a break for the door. If they manage to stagger that far, all they get for their trouble is a bullet in the back.

Only a minute has passed in the Lecture Hall’s training routine before the room has completely cleared of Mogs. The Garde usually have to endure seven minutes before they get a break during the training portion. I guess they don’t have anyone shooting real bullets at them, though. I reach up and slap the controls on the Lectern until the system shuts down.

“That worked!” Sarah yells, sounding almost surprised. “We got them, Sam!”

As Sarah stands up, I notice a burn mark on the outside of her left leg. Her jeans are torn, the skin beneath them a burned pinkish where it isn’t bleeding. “You’ve been shot,” I exclaim.

Sarah looks down. “Crap. I didn’t even notice. Must have just grazed me.”

As the adrenaline dies down, Sarah limps over to me. I put my arm around her for support and we move as fast as we can out of the Lecture Hall. We grab more guns on our way out. I tuck a second pistol into the back of my jeans just in case I run out of ammo. Sarah drops her spent handgun and grabs some crazy-looking lightweight machine gun, the kind of thing I used to believe didn’t exist outside of action movies.

“You know how to use that thing?” I ask.

“They all work pretty much the same,” she replies. “You just point and click.”

I could almost laugh if I wasn’t so worried about my dad and the comatose John and Ella. We don’t hear any sounds of fighting as we pass through the wrecked workshop, picking our way carefully over the junk we knocked over. The penthouse is eerily quiet. I’m not sure if that’s a good sign or a bad sign.

I poke my head into the hallway. There’s no sign of anyone. The floor is covered with Mogadorian ash, but otherwise all is quiet. The loudest sound is the wind blowing through the building thanks to the Mogs having broken every single window on their way in.

“Do you think we got them all?” Sarah whispers.

In answer, we hear a shuffling noise from the roof that sounds like boots running across it. There must be more Mogadorians still up there and they’ll be massing for a second wave any second now, as soon as they figure out their first group has failed.
