Recommended Smart Action/Sci-Fi Novels

After discovering the Vorkosigan Saga, Snow Crash, The Culture Series, The Expanse Trilogy and rereading The Forever War I'm trying to find more Science Fiction novels that combine exciting action with smart/smartly executed story telling. Now to clear things up, by "action" I don't necessarily mean Military Sci-Fi(although those shouldn't be excluded) I'd like more variety like cyberpunk or present based science fiction.

 

dune by frank herbert will blow your mind
old mans war by john scalzi
childhoods end by arthor c clarke
brave new world by auldous huxley

spelling is off on some of these but google will fix it.
