"What are you doing?" shouts Piers voice from the door. He sounds suddenly terrified. "Sitting," I tell him. "Get down, right now." "I thought you love it up here," I point out, not looking behind me. "I do. But I don't want you up there, at least not alone. I'm not okay with that." I feel his arms lace around me, both tight and gentle at the same time. He pulls me from the ledge, placing me on the roof top where we both sit. "Please don't do that again."
