Brandy Schillace, editor-in-chief of the journal Medical Humanities at the time her review, writes in The Wall Street Journal that O'Sullivan "uncovers... complex mechanisms while painting a picture of psychosomatic suffering that removes its associated stigma, and she asks us to think about illness in new ways."
