Don't Let Me Go (Harry Styles fanfic)

Kacey fell in love with him the summer of '08. What they had was a connection, the first-love kind that reels you in until you realize you're hooked. Harry knew all too well the affect he had—and has—on her. Their relationship was a game of keep away until it got serious.
Kacey spent every summer at her Grandmum and Grandpa's house in Holmes Chapel, Cheshire, UK, while she's actually from the US. Harry Styles was her summer love for a long time. But... Something just stopped between them, severing their connection.
She dealt with the pain up until one summer, one Hawaiian vacation, a proposal, and when she thought she had a second chance it all fell dead apart at a place where her hands met those of a certain green eyed, curly haired boy for possibly the last time because a few words slipped and something was uncovered that wasn't supposed to be.
Everything twists around, bending and breaking down like a photograph in a bed of broken glass thrown at the loss of so much, too much.
Was this bed ever made for two, or will these lights blind everyone and cause everything to slam together and leave everyone sleeping alone, in their own sheets under what once was a perfect sky that's now torn?
