Red rising or Sun eater for more sci-fantasies like dune. For harder sci fi like weir I’d check out the three body problem or dark matter. I haven’t read it yet but Scion by James Islington also just came out. Hes my favorite fantasy author but if that carries over into sci fi I bet it’s amazing as well. Might be worth looking into

Hyperion series?

I agree with #1 on Red Rising by Pierce Brown also Will of the Many by James Islington if you’re interested in slightly more fantasy type sci-fi I’d look into any Brandon Sanderson book (the way of kings, mistborn, or skyward) The Shadow of What Was Lost by James Islington if you want a quicker read that is more sci-fi comedy look into All Systems Red by Martha Wells
