This was a fast, informative, and enjoyable read. I initial picked up this book for a reading challenge, having enjoyed Juli Berwald's other book Spineless, and wanting to see if I could get to understand my own OCD diagnosis better through understanding that of her daughter. While that isn't what I got out of this book, I still greatly enjoyed it. Framing coral health to the health of the planet, as mental health is to the health of the body, especially in how both have been consistently ignored until they reach near catastrophic extents clarified quite a lot about the coral reefs and what they do for the planet, that I had not been aware of before. That frame made the more scientifically dense sections easy to understand.
