Boring as sin. The reader of the audiobook did it no justice. (Note: the reader did a wonderful job in Forging Hephaestus and its sequel, just not in this outting.)

It starts strong enough with a lot of world-building and some interesting tech that facilitates deep internal conversations. But then it gets bogged down in dialogue and exposition, drags onwards for hundreds of pages, and ultimately there's no payoff for your efforts. It has lots of potential and maybe future books will be better in the series that it sets up, but I won't be reading them.
