I heard about The Water Knife on Books on the Nightstand, where they were discussing cli-fi or climate-fiction. Their summary of a dystopia plagued by climate change where water shortages leave everyone in the American Southwest vying for control of various water rights hooked me immediately. Since I live in Arizona, water scarcity is a topic that truly frightens me. And this book flew by for me.
The first 100 pages I read in a couple of sittings. Once the plot took off, though, I had one of those nights where I was up well past my bed-time turning page after page dying to know what would happen next. I finally had to force myself to sleep and I picked up the book two mornings later and finished it.
