The Hike by Lucy Clarke

Maggie, Liz, Helena & Joni. Old friends bound by history, adventures, old secrets. And now, bound by murder. They lace up their hiking boots for the adventure of a lifetime in the Norwegian wilderness: a place of towering mountains, glass-like lakes, log cabins and forests stolen from a fairytale. It’s the perfect place to lose yourself – until a broken body is found at the bottom of a ravine. Somewhere out there, someone knows exactly why a woman has died. And in this deep, dark wilderness, there’s a killer on the trail . . .
