I found this book to a very fast pace read. I thought the world building and science was so interesting but I did sometimes get lost in the details. I thought that the world building because it was a mystery felt like massive info dump near the end and just wanted more time to process the ending. I did not feel super connected to the characters but I really loved reading the book. The pacing was overall quick pace but had slow moments towards the middle of the book. I def did not send the massive ending coming and found that to super cool. I am really am exited to read book 2 soon!
