Chloe Clark. That's me. The girl who's dating an amazing boy and just had the summer of her dreams. And there's only one more school year until independence day. Everything was fine. Perfect - as perfect as a teenage girl's world could be. Until I got a Tattoo. No I didn't do it to piss off my Mom, I never even wanted body ink. It showed up out of the blue. The strange headaches, dizzy spells and sharp senses might have something to do with this strange three-spiral Mark. Then there's this strong smell, it calls to me, pulls me to certain people. That same smell clicks a thought in my brain. Turning on a predatory switch. An instinct to kill. Something deep inside me has been sleeping and this Mark, whatever it does or means, it awakened it. But the worst part of it all, is that the people I'm attracted to kill also want to kill me.
