Sequel but stand-alone story

[Martin]

I just finished Planetfall and am super excited for this book.

The author said on her blog: "It’s called After Atlas and is set on Earth forty years after the Pathfinder took 1000 people into space to find God. It is also a standalone, just like Planetfall is." So far, that's all I've found out about it. (And it's really all I need to know.)
