I just finished reading Mike’s newest book, A Long Time Until now. It’s a typical MZW in terms of pacing: a slow first chapter followed by rapidly accelerating pace of story-telling all the way up to the last sentence. It’s not a typical time travel book, though the details of historic and future-historic living are superbly written. It’s more of a drama detailing how different societies and cultures deal with sudden disruptions, and how the challenges of heterogeneity become strengths under fire.
I would recommend getting the pre-release digital version and not waiting for the paper edition. This book kept me awake for a few nights, so why should you get any more sleep than I have!
