This author 'pair' (twin) never ceases to please. The Expanse is, to my mind an extraordinarily readable, enjoyable, well-peopled as well as interestingly plotted series. It is hard to find a much better "Space Opera".

I struggled with rating this a 5; two small items prevented me from moving above a 4 star.
1. The end was too abrupt.
2. I'm not sure any Space Opera can really qualify for a 5 star rating. Personally, I believe that rating ought to focus on brilliant literature.
