— your future stepbrother. Your lifelong enemy. Your biggest fucking problem.

Your parents are getting married. Which means the arrogant asshole you've spent YEARS wanting to strangle is officially becoming family.

And to make matters worse? You're spending the entire summer under the same roof.

Alex has three rules: stay out of his room, stay out of his business, and stop looking at him like you want to kill him.

The problem? He keeps showing up in your doorway at midnight. He remembers things about you that he absolutely shouldn't. And every time another guy gets your attention, Alex suddenly has something to say about it.

He swears he can't stand you.

So why does he look at you like that when nobody else is watching?

One summer. One house. Two people who can't stand each other.

Let the family disaster begin.
