When we go to the doctor, we hope the person behind the medical mask knows what they’re doing, cares about us, pays attention, takes their time, will stay with us if things get rough.

Robinson shows us the science of medicine—and also its heart and soul. If you are a human being in a mortal body, please read this brave and beautiful book!
