This kind of nonfiction relies on earning the privilege of entry into people’s lives and observing them closely and deeply; Hobbs excels at both. Describing environments and scenes, he is fluent and precise, with an eye for rich detail. Even better is his portrayal of the internal experiences of his subjects, showing the reader their coping mechanisms, loneliness and depression. Hobbs’s prepandemic access is formidable, as is his ability to reconstruct those scenes that occurred after in-person reporting became impossible.
