This is a fascinating study of one of the most important and tragic public health events of our generation. It traces the trajectory of the struggle over the definition of AIDS, the slow institutional response, and the dynamics of "blocked action" and finally "getting action" through the medium of action networks. It is a brilliant combination of detached observation and compassionate understanding - a must read for the activist insiders and a lesson for the rest of us watching a crisis unfold and wondering how to react.
