It's incredible the things we know, the things we think we know, and the things we expect other people to think about. We are able to live because other people are thinking about drinking water, sanitation, etc. We don't think about what happens when something goes wrong. 

Dr. Mona Hanna-Attisha was one of the ones that raised the alarm during the Flint water crisis and used medical science to show how the change in water source contributed to higher levels of lead in the blood.  The books is that story, but it's also the story of public health in general. As with many other books, Dr. Mona fills the story with history and other examples to fill in the dots. 

The book is successful and not nearly as bleak as I thought it would be. I learned a lot about the public water, the Washington DC water crisis, the history of lead, the history of Flint, the racial history of Flint, and the tenacity it takes to make change. It helped me understand the importance of having good people in government roles that are looking out for their citizens. She also does a great job of explaining health equity and how factors such as poverty and where one lives can have long term effects. 

Overall a really good book about medical science, public policy, and government malfeasance. Dr. Mona does a great job of showing how the pieces fit, who we should be thinking about, and why it matters. Highly recommend.
