I’ve been on a cosmic horror kick lately, and what I’d really like to read is stories or novels of the awful and unfathomable on a spaceship. Stories where we go to them, poke what shouldn’t be poked, scan what shouldn’t be scanned, and things proceed from there.
Probably not exactly what you have in mind, but I’d still recommend The Reality Dysfunction (and the other two books in the Night’s Dawn Trilogy) by Peter F Hamilton.
