I saw his body change. He crouched on the rooftop, one hand gripping the ledge. All that strange friendly feeling vanished, and now he was a hunter. This was something I recognized, something I felt comfortable with because I understood it. I shut off my brain. It was time for the hunt. I took a deep breath, inhaling the scent of the blood of the people down on the street. They weren’t the only ones around, but they were the closest. Who you would hunt was a decision you had to make before you caught a whiff of your prey. Now it was too late to choose.
