Like the title! I've been getting back into reading for pleasure, and want to know what you like! I recently read Piranesi and loved it. I've heard good things about The Poppy War and Babel by R.F. Kuang, has anyone read them?
Generally just want a bunch of recommendations from your favorites, on our commie corner of the internet. No genre needed! 
I remember genuinely enjoying Brian Jaques' Redwall book series to the point I'd recommend them even if they're considered 'children's books'. Vernor Vinge's A Deepness in the Sky is another favorite book of mine that still sticks out to me to this day, I never had a chance to read Vinge's other works sadly but that may be an interesting series to delve into. I'd also recommend John Steakley's Armor, though some might consider it a bit of a more mediocre title or even ill-fitting of the audience here.
its a shame I don't really have much more in terms of recommendations considering the quite literal thousands of books I've read in the decades where I read with seriousness. Honestly reflecting on it makes me sad. So much time spent relentlessly racing through pages, and almost none of it was spent reading any of the legendary classics of literature even when it was of the genres that I enjoyed. And none of it has stuck to my mind to this present day
Vinge's A Fire Upon the Deep is in the same universe (and shares Pham Nuwen) as Deepness. It's partially out of the Slow Zone where Deepness happened, and partially on a planet of Swarm Doggos, where each individual is the emergent result of four-to-six nonsapient dogs linked up through organic ultrasound organs.
The spiders are neat, but the dogs are really cool.
Children of Time by Adrian Tchaikovsky is another good spider sci-fi book. Humans wipe themselves out, leaving our various hubristic experiments to survive and evolve over tens of thousands of years (megalomaniac scientist wanted to play god with smart monkeys, accidentally created smart spiders).
Wild. If it wasn't for my now milder arachnophobia, a result of showing the movie arachnophobia to a toddler, I'd be quite interested in reading the direction Adrian takes his story premise.
