No Safe Water — Grace Hamilton

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.
