The Tao of Bill Murray
"The Last Battle" by Cornelius Ryan , is a great book if you like Hardcore History, its basically a Dan Carlin podcast in literary form, and some of the stuff is mind-blowing, its about the battle for Berlin in WWII and the craziness of the last moments of the capital.
I scoured around goodreads to find something to read along the lines of "if you like The Expanse, you'll also like" and ended up giving the Luna trilogy by Ian McDonald a spin. I'm almost through the second book and while it's not The Expanse, it's pretty damn good. It's set about 80 years after the first commercial/industrial colonization of the moon which means the tech is more science than fiction.There's a dash of cringy sex in there that isn't my favourite, but overall it delivers some strong emotional beats and interesting characters. There's even some interesting speculative psychiatry around what social constructs might develop around mental disorders in this version of the future. Here's the goodreads link to the series: https://www.goodreads.com/series/166174-luna
