"What's wrong?" Summer asked the second we stepped into the main hall.
The space opened up wide around us in a big circular shape, the kind of place that probably looked impressive as hell before the world collapsed. Several escalators cut up through the center, stairs rose off to the sides, and storefronts ringed the whole floor from every direction. Open sightlines. Too many angles. Too much space.
Which also made it a perfect place to get boxed in.
And, right on cue, I could already see movement.
Infected were starting to gather below and around the edges, drawn in by us, drifting first, then fixing onto our position.
"Nothing," I said. "Let's move."
Summer nodded and started up one of the dead escalators, taking the steps quickly. I followed for a few seconds, then stopped her halfway by catching her arm.
She turned and frowned at me. "What is it? You've been acting weird ever since I said I wanted to come back here."
