is the book all America needs to be reading as the COVID-19 pandemic rages on. Written by bestselling authors Dr. Judy Mikovits and Kent Heckenlively, this book reviews the evidence for and against widespread public masking as provided by the Centers for Disease Control and the Mayo Clinic, as well as top scientific publications such as the and . This debate needs to take place without fear and paranoia. Important questions raised in this book are the effect of masks on oxygen and carbon dioxide levels, how COVID-19 spreads, the effectiveness of various types of masks, those who are most vulnerable to COVID-19, and what measures should be taken by schools as children continue to return to in-person classes. The authors' previous book, , was the runaway science bestseller of 2020, and the authors bring that same passion and attention to detail to the mask question. As politicians and bureaucrats of all stripes are weighing in on this question, with some again placing their cities and states under mandatory masking provisions, we need to understand the science behind their decisions. Are such measures a reasonable response to current circumstances, or is it a dramatic overreach, which in many cases might make the situation even worse? America desperately needs this public conversation to take place with the best science we have available. As Americans have always done during difficult times, we must summon the courage to have these challenging conversations.
