The gymnasium of the Upper East Side Preparatory smells of desperation and hairspray. Not the Constance Billard kind. The competitive cheer kind.

Blair Waldorf, in a sequined red and gold crop top, stood before her pyramid of perfectly glossed minions. “A triple-base basket toss is not a suggestion! It is a mandate! My mother’s seat on the International Cheerleading Federation board depends on us beating the Brooklyn Heights Cobras, and I will not have my legacy jeopardized by weak wrists!”

From the bleachers, Chuck Bass swirled a bottle of water like it was 30-year-old Scotch. “I’ve funded better-looking revolutions in third-world countries, Waldorf. But the legs? I’m a patriot.”

The doors burst open. Not with a bang, but with a blinding, sun-god smile.

Serena van der Woodsen, a duffel bag slung over her shoulder, her hair in artfully messy double buns, blinked into the fluorescent light. “Sorry I’m late! The subway from Brooklyn was a nightmare.”

The gym fell silent. Blair’s smile could have chilled hell.

“Van der Woodsen. You’re not just late. You’re geographically inconvenient. And you’re wearing the wrong colors.”

Serena dropped her bag, revealing a Cobras practice jacket underneath. She shrugged it off, showing a UES Toros tee beneath. “Let’s just say I had a change of allegiance. Brooklyn was getting a little… predictable.”

Nate Archibald, the flawless back-spot with a heart of gold, nearly dropped his flyer. “Serena? You moved to Brooklyn?”

“A girl needed a fresh start,” she said, her eyes locking with his. “Turns out, some things you can’t outrun.”

Blair watched the exchange, a plan crystallizing. Serena was a natural talent, a human cheat code. She could win them the regionals. She could also steal Nate, again, and unravel Blair’s perfectly constructed world. Again.

XOXO
