The Expanse keeps rumbling on. This was a good 'un. The timeline is moved on a few years and many plot threads are wrapped up. They are certainly narrowing down to a denoument now (having said there will only be 9 books). This had moments of true wonder and true sadness. A definite recommend (as is the whole series). A small note, it would be best to have read the novella Strange Dogs before launching into this as it gives some background to an important plot mechanism.
