From USA Today bestselling author Brooke O'Brien comes a small-town, brother's best friend football romance about a guy who swore she was off-limits—but some lines were meant to be crossed.

Football rules everything in our small town. Under the stadium lights of the Gridiron, no one plays under more pressure than Zane Kinnick—the hometown legend and future NFL star who's spent his life proving he's built for the spotlight.

And me? I've always been the one risk he wasn't willing to take.

I've loved Zane for as long as I can remember. My next-door neighbor. My brother's best friend. The boy who swore I was off-limits.

For years, he kept me at a distance—until the night we finally gave in.

Then he walked away like it never happened.

Now, he's done pretending. The stolen glances have turned into lingering touches. The tension we ignored is finally snapping. And for the first time, he's tearing down all the walls he's built between us.

But we aren't the only ones holding on to the past. His rival is out for blood, using me and the people he loves to get inside his head, feeding him lies, and twisting the truth.

Because this rivalry? It's not only about football.

It's about secrets that refuse to stay buried. And when the truth finally comes out, it won't just change the game—it'll shake up his world.
