Loneliness is not solved by being around more people. Half of it is internal, the part that does not feel met even in a crowd. The other half is structural, the relationships and rituals that have quietly thinned out. These books cover both. Some are about the kinds of relationships our culture undervalues, some are about what gets in the way of intimacy, and one is about the practice of paying attention to another human being like it matters. Because it does.
