Interesting and so much fun. I'm going to love this series. This is a different universe for Scalzi: the planets are mostly not habitable on their surfaces, The universe isn't full of fascinating intelligent species, although there are a fair number of humans scattered about. Two of the main protagonists are women, both of them clever as hell, one also profane as hell. Her language, her incredible, individual, hand-crafted bespoke foul language is one othe the lightest and best ongoing jokes.
The story is concerned with a colonized universe, a new emperox of same, a clever mathematician, a clever foe, political machinations, and much of it slower than slugs because of the time constraints on communication.But even though the timeline is lengthy, the books never flags. It zips on, only filling in small amounts of the gaps.Oh, the depths of those plots!
It reminds me a bit of some of the Foundation books, except with a lot more humor. It more closely resembles Scott Westerfeld's novels of his Succession empire.
Scalzi does a great job of keeping the story grounded, while also maintaining his sense of humor.
