Ryan McCullough and Gabby Hart are the unlikeliest of friends. Introverted, anxious Gabby would rather do literally anything than go to a party. Ryan is a star hockey player who can get any girl he wants—and does, frequently. But against all odds, they became not only friends, but each other’s favorite person. Now, as they face high school graduation, they can’t help but take a moment to reminisce and, in their signature tradition, make a top ten list—counting down the top ten moments of their friendship:

10. Where to begin? Maybe the night we met.
9. Then there was our awkward phase.
8. When you were in love with me but never told me…
7. Those five months we stopped talking were the hardest of my life.
6. Through terrible fights…
5. And emotional makeups.
4. You were there for me when I got my heart broken.
3. …but at times, you were also the one breaking it.
2. Above all, you helped me make sense of the world.
1. Now, as we head off to college—how am I possibly going to live without you?

It was always meant to be Olivia. She was the talented one, the one who had been training to be a star her whole life. Her best friend, Dana, was the level-headed one, always on the sidelines, cheering her best friend along.

But everything changes when Dana tags along with Olivia to Orlando for the weekend, where superproducer Guy Monroe is holding auditions for a new singing group, and Dana is discovered too. Dana, who’s never sung more than Olivia’s backup. Dana, who wasn’t even looking for fame. Next thing she knows, she and Olivia are training to be pop stars, and Dana is falling for Alex, the earnest, endlessly talented boy who’s destined to be the next big thing.

It should be a dream come true, but as the days of grueling practice and constant competition take their toll, things between Olivia and Dana start to shift . . . and there’s only room at the top for one girl. For Olivia, it’s her chance at her dream. For Dana, it’s a chance to escape a future that seems to be closing in on her. And for these lifelong best friends, it’s the adventure of a lifetime—if they can make it through.

Set in evocative 1990s Orlando, New York Times bestselling author Katie Cotugno’s Fireworks brings to life the complexity of friendship, the excitement of first love, and the feeling of being on the verge of greatness.
