Two boys. One heart. One love she never meant to create.

Sapphire Sullivan has spent almost a year trying to forget the only boy she's ever loved. One stolen kiss with her brother's best friend changed everything. When Jack Murphy called it a mistake, Sapphire promised herself she'd stop wishing for something that could never be.

Then Labor Day weekend brings him back into her life.

Under the glow of carnival lights and an endless September sky, Jack looks at her the way he used to. Old feelings ignite, forgotten dreams come rushing back, and Sapphire starts believing that maybe first love deserves a second chance.

Until someone else appears.

Jett is the kind of boy who only exists in stories. He's beautiful, mysterious, and seemingly devoted to only her. There's only one problem-no one else can see him.

Except Jack.

Sapphire doesn't know why Jett came into her life, what connects him to Jack, or what he truly wants from her. But as strange moments become impossible to ignore and the line between the real world and something more begins to blur, Sapphire is forced to question everything she believes about love, fate, and the stories we tell ourselves.

Because sometimes the hardest choice isn't between the past and the future. It's between the story you've been writing... and the life waiting to be lived.
