I wasn't sure I wanted to read (listen to) a book with the premise "What if COVID19, but much much worse",. but I'm glad I did.
The best speculative fiction is often a vehicle for commentary on contemporary life, and this book definitely is that, both on big themes, and perhaps more interestingly on the quirks and foibles of life in the 21st century.
The characters are nicely drawn and interesting. In a strange feat, I am now a fan of a fictional comic book series that I have only heard someone describe.
There was enough suspense and plot to keep me interested, without indulging in an excess of action. There some slightly implausible coincidences, but they don't drive the plot, but serve more like decoration.
