That cover looks dope
A recent unexpectedly good read in sci-fi was Nightside City by Lawrence Watt-Evans. I was going through everything he wrote but it's mostly other genres so I thought the one-off sci-fi book will suck. I was wrong, it delivered a fast-paced, grippiing noir detective story in the future. My only con to it is that it has no sequels, I like that character enough for a 10+ book series.
"Give sci-fi suggestions" is a bit broad. What did you already read and like in the genre? Did you already go through the essentials: Bradbury, Asimov, Wells, Brin, Herbert? What tropes/themes do you like/dislike to read about?
