Second book in The Expanse trilogy, and this one is really well done, with plenty of action and some believable technical details. I read the first book last week, my local library is well-stocked with current SF!
I can’t help being reminded by Paul McAuley’s Quiet War universe, set in basically the same place in the Solar system and with similar tensions. They’re both very good but Corey’s books are more pure space opera. Read them all and compare!
