Babylon’s Ashes by James S. A. Corey (The Expanse, Book Six)
Always interesting to compare these books to the TV series, especially re. character changes. Perhaps the best example is Michio Pa, who’s the basis for TV’s Camina Drummer. Also, Marco Inaros is just one of those characters that you love to hate. I’m consistently impressed with Corey’s ability to balance the horrors of war with an underlying optimism.
