Then she was up and out the window, dashing for the nearest vehicle. Peter scrambled into position. The darkness beyond was total, the moon obscured by the roof of the portico. He heard a soft impact as Alicia took cover at the base of one of the Humvees. He pressed the stock of his weapon tight against his shoulder, willing Alicia to whistle the all clear.

Beside him, Hollis whispered, “What the hell’s keeping her?”

The lack of light was so complete it felt like a living thing, not an absence but a presence, pulsing all around him. An anxious sweat prickled his hair. He drew a breath and tightened his finger on the trigger of his rifle, ready to fire.

A figure raced toward them out of the darkness.

“Run!”

As Alicia dove headfirst through the window, Peter realized what he was seeing: a roiling mass of pale green light, like a cresting wave, hurtling toward the building.

Virals. The street was full of virals.

Hollis had begun to fire. Peter shouldered his weapon and managed to let off a pair of shots before Alicia seized him by the sleeve and yanked him away from the window.

“There’s too many! Get out of here!”

They had made it less than halfway across the lobby when there came a thundering crash and the sound of splintering wood. The front door was failing; the virals would be streaming in at any second. Up ahead, Caleb and Mausami were sprinting down the hall toward the casino. Alicia was firing in quick bursts behind them, covering their retreat, her spent shell casings pinging across the tiled floor. In the flashing light of her muzzle Peter saw Amy on all fours by the piano, probing the ground as if she’d lost something. Her gun. But there was no point in looking for it now. He grabbed her by the arm and pulled her down the hall, chasing the others. His mind was saying: We’re dead. We’re all dead.

Another crash of breaking glass from deep inside the building. They were being flanked. Soon they’d be surrounded, lost in the dark. Like the mall, only worse, because there was no daylight to run to. Hollis was beside him now. Ahead he saw the glow of a light stick and the figure of Michael ducking through the shattered window of a restaurant. As he reached it he saw that Caleb and Mausami were already inside. He yelled to Alicia, “This way! Hurry!” and shoved Amy through, in time to see Michael disappearing through a second door at the rear.

“Just follow them,” he cried. “Go!”

Then Alicia was upon him, yanking him through the window. Without a pause she reached into her pouch and withdrew another light stick and cracked it over her knee. They raced across the room to the rear door, which was still swinging with the force of Michael’s exit.
