This was unexpectedly amazing! (Unexpected because I knew nothing of the book before I started listening to it.) I was looking for a great audio book for a road trip, and this was so good that I did the thing where you sit in your car after you get home because you can't stop listening (after driving for almost ten hours!). Humans find evidence that there are other species in the universe, who have a much more advanced society than theirs. In this first book of the series, we follow the ragtag team of people involved in understanding the alien technology and how the discovery changes all of their lives.
