The Long Water By Stef Penney

Daniel, a popular teenage boy, has gone missing from his tight-knit community in the Norwegian Arctic. Conflicting stories circulate among his friends, of parties and wild behaviour. As the search for Daniel widens, the police open a disused mine in the mountains. They find human remains, but this body has been there for decades, its identity a mystery. Everyone is touched by these events: misanthropic Svea, whose long life in the area stretches back to the heyday of the mines, and beyond. She has cut all ties with her family, except for her granddaughter, Elin, an outsider like her grandmother. Elin and her friend Benny, both impacted by Daniel while he was alive, become entangled in the hunt for answers, while Svea has deep, dark secrets of her own.
