I want to thank NetGalley for the ARC of this book. It’s a truly fantastic premise reminiscent of Project Hail Mary. The characters are likable, but not always given the most depth to truly be moved by them. It has moments of hard sci-fi which get lost toward the end. The pacing is good as it covers many years, however the separation between time periods is occasionally jarring as you didn’t realize how much time had passed between sections. Overall, I enjoyed the book and can’t wait to try more by this author.
