Sarah and Summer travel to the Maldives for one last adventure before leaving for university abroad, believing it will simply be a carefree farewell to their youth. But paradise becomes the setting for a meeting that will quietly alter the course of Summer’s life. There, Summer meets Callum—a gentle dreamer living with a fragile heart. As his illness reminds him that life can be painfully short, Summer battles a different kind of a heart guarded by fear and unresolved trauma. What could have been the beginning of a great love story slowly suffocates beneath the weight of everything Summer cannot face. Ten years later, Summer returns to Manhattan, not to reunite with Callum, but to say goodbye at his funeral. And there, among grief and unfinished memories, she meets Cage—Callum’s older brother. What begins as a painful reunion soon becomes something neither of them expects. As Summer and Cage are forced to confront the past they share, they discover that their lives have been intertwined far longer than either realized—and that healing old wounds may be the only way to finally find happiness.
