I loved the Expanse series, but like Hyperion better. Has the literary structure of Canterbury Tales if you’ve read that. The story spans four books and doesn’t click entirely until you reach the last part of the last book. It’s fantastic. (I’m rereading the series)

Hyperion is a bit more futuristic, but a lot more asymmetric compared to Expanse, keeping it fresh. It’s ideas and ethics go a lot further. It asks and answers questions that people are currently concerned about, or could soon be concerned about, give or take a century or two. I won’t spoil it, but it’s excellent sci-fi. The author clearly did a lot of research while writing it. :)
