A porcupine has more than one point to make about how climate reality impacts his new fish friends, a Rio Grande silvery minnow and a razorback sucker. Together they trek across the desert southwest meeting other animals endangered by human-caused changes. Those other animals have information to share, but some of them, like a grumpy Bald eagle, consider turning the fish into breakfast. Dodging hungry predators and figuring out that rising carbon dioxide levels both pose a threat to these animals is just part of their adventure. Yet their journey includes some stories of hope, like when they meet Elaine, a young community scientist who tracks environmental change and cares for land and water with kids from her school. It might be hard to be a fish in a desert, but it’s not impossible.
