The summer after everything changed, Belly Conklin can't imagine going back to Cousins Beach. The house that held all her happiest memories now holds a loss she isn't sure she can face, and the two boys who defined those summers—Conrad and Jeremiah Fisher—are grieving in ways that pull them further from her and from each other.
When Jeremiah calls to say that Conrad has disappeared and the beloved beach house may be slipping away for good, Belly drops everything to help. The three are drawn back to Cousins one last time, forced to confront what they've lost, what they still mean to one another, and whether first love can survive real grief.
The second book in Jenny Han's trilogy, It's Not Summer Without You deepens the story into something quieter and more aching—a coming-of-age about mourning, family, and the stubborn pull of the people we grew up loving.
