Wicked Games by Willow Dixon

Killian
I hate obscure school rules. Especially the one that says siblings have to room together after a tragedy. Now I’m stuck sharing my dorm with my stepbrother, and I have no idea how either of us is going to make it to the end of the school year without offing the other.
Just as I’m getting used to having Felix around, someone else tries to off him, and now my cousins and I have to figure out who’s after him, and why. We might not like each other, but Felix is family, and that means he’s mine to protect.
Felix has always annoyed the hell out of me, but now he likes making me angry. And unlike most people, he isn’t afraid of me when I’m angry. There’s also something else between us. Something wild and addictive.
Something I’ve never felt before.
I’ve always known there’s more to my buttoned-up stepbrother than meets the eye, but it isn’t until we start a game of gay chicken that I realize just how similar we are.
He should know better than to start a game he can’t win, but if that’s what he wants, then game f*cking on, bro.
