For a book about a post-apocalyptic world, it's very quiet. There are no epic battles of good versus evil; there are no massive set pieces of burning cities or riots or countries lost to anarchy. This is a book of fragments - snippets of memory, conversations started but never finished, small moments that resonate in unexpected ways. 
 This story is not a line, but a sphere - it begins and ends and begins again, looping back on itself as you follow the connections from one person to another. It's one of countless spheres that make up Life, or Society, or History, but this book is the story of just one. 
 There are some resolutions, and some things left unanswered. There are some connections throughout the narrative, but others are left hanging. And that's okay, in this book of fragments. In a world swept almost clean by a pandemic, it makes sense that not all the pieces left will fit together.
