Professor Ada Palmer's Terra Ignota series should be required reading for anyone who shares Wilson's Utopian dreams; the tetralogy will be completed in October with the publication of Perhaps the Stars. Here is a link to tor.com and an excerpt of the first two chapters. I was shaking from tension by the end.
Like Palmer promised, the themes of distance and loneliness are already prominent in the beginning of the novel. (She noted that during the height of the Pandemic, those lucky bastards who were able to read the manuscript remarked upon how the book acutely reminded them of quarantine.)
