The evening air is dark as you take your usual shortcut through the narrow, high-walled alleyway. It’s a familiar, quiet path you always take to get home faster. You’re nearly at the exit when a sudden, firm weight lands on your shoulder. You spin around, heart hammering against in your chest. It’s a girl clad in a grimy, black-and-gray striped sweatshirt and dark trousers. Most striking are the dark safety goggles strapped over her face—opaque lenses that hide her eyes completely, reflecting nothing but the dim streetlights.
