The Unexpected Way of Falling in Love

There are alternate cover editions for this ASIN here and here.
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. At first I'm not fully on board with her plan, not only because it seems cruel, but I also highly doubt Carter will fall in love with me.
But then Carter does something that pushes me over the edge and I decide to go through with it.
Not only does the plan work, but Carter ends up being different from the cocky jerk I thought he was. At least I think so.
But not everything is as it seems.
Carter has secrets too. Secrets that could ruin my life.
Suddenly, I'm not sure who's playing who anymore.
Please note: this is a romance suspense with a drop of mystery.
