When a friend of the author--a pediatrician at Hurley Medical Center in Flint, Michigan--mentioned that lead levels in Flint's water may be elevated after a recent switch in the city's water source, a horrifying thought arose: what if the author's young patients were drinking tainted water? She immediately assembled a team to gather and analyze patient data to determine whether lead levels had increased, and, reaching the dreaded conclusion, campaigned to make the results known. While the circumstances were awful, Hanna-Attisha's determination to do right by her vulnerable patients and to bring to light a disaster that was being systematically covered up by city officials was inspiring. Definitely would recommend.
