The Final Architecture by Adrian Tchaikovsky, especially if craving more space opera. Children of Time and Dogs of War, both fantastic series also by AT. Almost everything by AT is great, so many original concepts and ideas, the guy is prolific af. Revelation Space by Alaistar Reynolds, The Culture by Ian Banks are both amazing with numerous books. Hyperion and A Fire Upon the Deep, some older but solid series. Red Rising if you’re into it, kinda YA.
