I’ve gone through (I think) the whole Culture series of Banks. Weirdly enough, they got recommended to me by a barber when I was ~15yrs. Sweet guy, he had no tv & read a shit tonne. I love the philosophical and/or societal talking points overarching each of Banks book most, I’m awful at recalling the actual stories. There’s identity crisis in Consider Phlebas, purpose in Player of Games, excession in the aptly named Excession, the list goes on really. Plus hyper sci-fi, so a bunch of wobbly physics and warfare situations going on. If you can’t tell, I love these books lol
Not sure about engines, but when you “break in” a horse that doesn’t seem like much of a “rest” for the horse. More so indoctrination or submissive tactics.
