The River Runs Backward

Three years after a river took a boy she swore to bring home, Antonia Bravo guides tourists down water that cannot hurt anyone. Then a satellite message arrives eleven days late from her estranged sister: coordinates in the Ventisca valley, a photograph of a milky lake swelling against a glacier, and eight words. The search is already closed. A hydro company owns every helicopter and radio on the coast. So Antonia goes the slow way — by kayak, by rope, by ice — into a valley that is quietly filling up with the flood that will erase a village.
