This is no review, this is a spoiler. Good thing I stopped reading not too far into this "review". Lol
Thank you for bringing up the book, though. I just got it and will read it.

Which book is it? I have a paywall.

What I loved but was left unsaid was the environment was a reflection of society.

The larger planet was "born" slightly larger and therefore with greater gravity. Over millions of years, it would slowly take the atmosphere (including water vapor) from the smaller planet until life could not exist on the smaller planet.

The planets reflected the capitalist society of the larger planet where the rich were slowly draining the poor.

Ahh my favorite author and my favorite book. I have a signed copy.. somewhere..

Just finished this a week ago, loved it
