There is a certain genre of science fiction where human beings find a massive and ancient alien artifact or ship. They explore that artifact while being completely ignored by the it and whatever attendants it may have (automated or otherwise). They marvel at the age and history and unfathomable alienness of the thing. Then they leave, having found more questions than answers but opening the eyes of our species to a new level of cosmic wonder.
When done well, books in this genre can be a page-turning adventure story about a group of people overcoming tremendous obstacles — all set against an amazing and rich backdrop. When done poorly, books in this genre become monuments to how much math the author has done to arrive at something fantastical yet plausible.
This book was done well. The characters are fleshed out and engaging. The ancient artifacts are compelling and they leave the reader with the same questions that it leaves the book’s human civilization: “Who built this? Where are they? Can we find them? Can we talk to them? Can we learn from them?” The other relics of other civilizations our heroes find have their own shades and layers of mystery, leaving the reader with even more questions and idle fantasies while painting a picture of an and well-populated galaxy. The adventures are fast-paced and exciting. The AI is charming.
And ultimately, the chief adversary of the humans in Chindi turns out to be the hubris of members of their own team. Which, in a book that chronicles the self-destruction of countless other civilizations, serves as a solid theme and a good reminder to not do that.
This book was both satisfying and entertaining. I look forward to finding other entries in the series.
