It's an absolute binge read. It's a compelling story with a lot of discoveries and exciting moments. There are many parts of the book that are absurd and can't possibly work, but the entire premise is absurd so I rolled with it and enjoyed the book for what it is. I found myself very attached to both Rocky and Grace as a result. It wasn't life changing, but as an optimist I always enjoy books where people work together to solve existential threats.
