The next book on my list is Winter World by A. G. Riddle, so this will be my very selfish suggestion. 😂

Lots of great recommendations here. I haven't seen anyone mention John Scalzi!

Both the Old Man's War and Interdependency series are amazing!

I haven't read Pandora's Star, but I love everything else on that list. Since we seem to have similar tastes, I'll give it a shot next!
