Patrick is my friend. My best friend. He’s every good girl’s dream come true. Funny, sweet and holy-hell hot. Perfect. So what’s the problem? I’m far from perfect and I’m no one’s idea of a good girl. I know that, but I’ve wanted Patrick ever since the first night we met. Ever since I kissed him and…well, did decidedly ungood-girl things to him in the front seat of his car. The same night he gently but firmly shut me down completely with a it was nice to meet you, Cari.

The night my sister died, a piece of me died with her. So I made a vow to enroll at Spine Ridge University just like her, find the person responsible… and make them pay. Until I meet three sick boys of the Skull & Serpent Society: Felix, Dylan, Alistair. Rude, heartless, vicious guys who are obsessed with making me regret I ever stepped foot on campus. They make me a deal: My body in exchange for a glimpse at their violence.

When Dad died, he made me the leader of the Italian Mafia. That position was unheard of for a woman—until me. Ryder, Dex, Gage, and Holden are my team, my closest friends. Then Leo waltzes into my life, turning it upside down, along with everyone in it. One lie. One secret. That's all it took to bring it all burning down around me. Jealousy and hidden desires from the four guys I thought only saw me as their friend and boss stoke the flames even higher.

They rule my new town, my school, and with more money than God, there’s very little out of their reach. Four gorgeous, perfect, scary boys. There used to be five, but one of them died, leaving a fifth position that I now fill. I didn't ask for this. I didn't want to be part of this billionaire-boys-club. But no one cares about what I want. Sebastian Beckett is the worst of them. Their leader. He draws me in, and strips me of every defense I have. He calls me Butterfly, but it's not a pet name, it's a threat.

I'm the girl you'll never see coming. Blink and you're dead—another target checked off my list. Until one night, my carefully ordered existence falls apart. A bloodbath and a car crash later, I find myself in the grasp of four gorgeous, intimidating men. My captors claim they're holding me for my protection. I can't quite believe that.
