Free Pure (Book 1, Pure Series) by Catherine Mesick

  Why did I feel like something was terribly wrong?
                As I waited in line with Simon at the cart, I started to feel overheated, so I took off my coat and draped it over my arm.   We were almost at the head of the line, and the guy ahead of us was just turning to leave, when he tripped and sent coffee spraying all over the place.
                I looked down and watched as several dark brown spots bloomed on my cream-colored sweater and began to spread out.
                "Are you okay?" Simon asked me.   "You're not burned are you?"
                "No, I'm fine," I said.   "I'd better go rinse these stains out before they set in.   I'll see you at lunch."
                I hurried to the girls' bathroom.   I briefly considered taking my sweater off to get at the stains better, and with that in mind, I checked all the stalls.   I was alone in the bathroom.
                But someone else could come in at any moment, so I decided to keep my sweater on and just do the best I could.
                I tore off several paper towels from the dispenser on the wall and went to a sink.   I turned on the tap and began to blot at the stains on my sleeve.   To my relief, the stains began to fade.
                I was just starting to work on the stain on my collar, when I heard a click from the door.   The door was hidden by a tiled wall, so I couldn't see who had come in, but I was definitely glad I hadn't taken off my sweater now.   What if it was Irina?   I didn't know if taking off my sweater to clean it was against school rules, but I had a feeling that Irina would tell on me anyway.
                No one came around the wall, so I figured I must have imagined the sound.   I realized that the bathroom door didn't click anyway – it creaked, so it probably wasn't the door.   I turned back to the stain on my collar.
                It suddenly flashed into my mind that there was a lock on the bathroom door – a crescent shaped tab at the top of the door.   I'd never been in the bathroom when it was locked, though, so I didn't know what locking the door would sound like.   I shrugged the thought off.   Who would want to lock the door to the girls' bathroom?
                I leaned toward the mirror to continue dabbing at my collar.   As I did so, I caught a flicker of movement out of the corner of my eye.   I looked up into the mirror and saw the dark-haired, blue-eyed guy standing behind me once again.
                I turned around.   This time, he didn't disappear.
                I felt a flash of panic.   The strange guy I kept seeing in weird places was actually standing in front of me.   He was staring at me steadily – the look in his eyes was dark, suspicious, and angry.
                Yet, he was strangely beautiful.   There was something perfect about the shape of his face and the long, lean lines of his body.
                Behind me, the water kept running.   For a long moment there was no other sound in the room.
                "Who are you?" he asked.   His voice was harsh, and he had an accent I couldn't quite identify.
                "Are you real?" I asked.
                He moved closer in one swift movement.   Suddenly, he was only a few inches from me.
                I began to feel light-headed.   Was he making me feel that way, or was I simply hallucinating?
                "Who are you?" he demanded.
                I could feel the warmth from his body, and I reached out a hand to touch his shoulder.
                "You feel solid enough," I said.   He did indeed feel solid, and I found I was reluctant to move my hand.
                So I wasn't hallucinating.   Somehow an image in a mirror had become real.   "How did you get out?" I asked.
