No one saw it coming. One day, the rivers flowed. The next, they were poison.
For Hazel Northrup, it's the day she escapes the only world she's ever known-a fanatical water-worshipping cult deep in the Oregon wilderness. With her little brother in tow, she flees into a dying world, vowing to keep him safe from both the toxic wasteland and the ruthless men hunting them. Miles away, a remote research team discovers something far worse than silence: water that kills. Stranded and grieving, scientist Emily, survivalist Bash, and their last remaining colleague make a desperate bid to escape the forest-only to collide with Hazel and Caleb. Forced into an uneasy alliance, the group must navigate a world unravelling by the hour. Wildfires rage. Disease spreads. And the cult, still hoarding clean water, is rising as a brutal new power. With supplies dwindling and the last safe haven miles away, survival isn't guaranteed. The further they go, the clearer it becomes: this isn't just a disaster. It's a collapse.
