PositiveThe New York Times Book Review...by focusing on mother-baby relationships, Denworth misses the fact that social brains can and do develop in the absence of mammal-style parental care ... Exploring friendship’s opposite — loneliness — throws the topic into poignant relief, especially when Denworth asserts that what’s striking about loneliness \'is not that those who suffer from it are peculiar, but that they are so ordinary\' ... Her account of research suggesting an association between loneliness and autoimmune disease, and her description of a dismal state known as the \'loneliness loop,\' are some of the most informative — and from a public health perspective, important — passages in the book.
