Regrets take over Cooper's life. Literally. As a radio host, she spends her days reading anonymous letters about heartbreak and regret on her segment Regret Radio, immersing herself in other people's stories to avoid facing her own. But no matter how far she runs, her past is always there, reminding her of the mistakes she's made. One of those regrets? Losing her childhood best friend. And it doesn't help that he's no longer just a memory, he's global superstar Harry Styles. He's everywhere. And just when she thinks she can escape through Regret Radio, a letter arrives that drags her straight back into the past.

"You know... We really are a fine line, you and I." "How so?" he asks softly. I shrug, staring at where our hands almost meet. "Because... we exist in all the spaces in between. There's a fine line between us being friends and being lovers, and a thin, terrifying line between us staying together or becoming strangers. There's a fine line between our world and the rest of the public, between the sun and the moon, between accepting the things that hurt us and turning them into something real... there are so many lines we stand between, Harry. But... I think that's what makes us who we are. Because there is no line for me to walk at all, if you aren't on the other side of it." ━━━━⊱⋆⊰━━━━ This is the story of two people helping each other grow. For Harry Styles, it's about figuring out who he is after leaving the world's biggest boy band. For Laudine Russell, it's about turning her love for photography into a reality by stepping behind the lens for him. Through music and photographs, they navigate the bittersweet journey of achieving their dreams, together. PLEASE READ THE AUTHOR'S NOTE & TRIGGER WARNINGS.
