"Lauren Cress teaches writing in the international program at a small college outside of Washington, D.C. In the classroom, she is poised, smart, and kind, well-liked by her students and colleagues. But in her personal life, Lauren is troubled and isolated. Still grappling with the sudden death of her parents ten years earlier, she exists at a remove from everyone around her, frozen in time as a grieving teenager. But one day, a new student joins her class: charming, magnetic Siri, who seems to be everything Lauren wishes she could be. As they fall headlong into an all-consuming friendship, Lauren sees a chance to reclaim her lost adolescence. When Siri invites her along on a trip home to Sweden for the summer, Lauren impulsively accepts. But as Lauren starts to find herself drawn to Siri's enigmatic, brooding brother Magnus -- much to Siri's resentment -- she starts to see a new side of Siri: selfish, reckless, self-destructive, even cruel. On the last night of her trip, Lauren accompanies Siri and her friends to a debaucherous outdoor party to celebrate Midsommar's Eve, a night when no one sleeps, boundaries blur, and, under the light of the unsetting sun, things take a dark turn. Ultimately Lauren must finally acknowledge the truth of her relationship with Siri and come to terms with her own tragic past in this gorgeously written, deeply felt debut about the relationships that mold us--for better or for worse."-- Provided by publisher.
