Seventeen years. That’s how long Jace has been my best friend. My confidant. My platonic other half. He’s the guy every girl wants, and I’m the girl who knows all his secrets—except one. It started with a dare. A ten-second kiss at a party that was supposed to be a joke. But it wasn’t funny. It was electric. It was intoxicating. And it was the moment I realized I didn’t know my best friend at all. Not in the way that truly matters. Now, the line we’ve spent our whole lives carefully drawing has been crossed. He’s looking at me with an intensity that steals my breath, and I’m drowning in the memory of how he tastes. But he belongs to someone else, and our secret is a spark in a school full of gasoline. They say some lines aren’t meant to be crossed. I’m terrified they were right.
