The Unexpected

I've had a crush on my best friend's brother for years. Which wouldn't be a problem, if he wasn't such a cocky jerk.
It's okay, though. My crush is based on shallowness, a simple attraction, so my heart isn't at risk of getting broken.
Well, that is until my best friend decides she needs to teach her brother a lesson and take his cockiness down a notch. Her plan: I'll get Carter to fall in love with me and then break his heart. 
Not only does the plan work, but Carter ends up being different from the cocky jerk I thought he was. 
At least that's what I think at first.
But Carter has secrets. Secrets connected to a dark, dangerous world. Secrets that could ruin my life.
