Project Hail Mary by Andy Weir.

Children of Time by Adrian Tchaikovsky.

I like so-called "hard sci-fi", where effort is made into thinking through the details and the sci-fi bit is not just a backdrop for a regular story, or a way to validate neuroses du jour. Both of these are definitely in my top-10 sci-fi books of all time.

I would not recommend 3 body problem. It may be because the French translation is bad but it felt really subpar.

I get the feeling 3 body problem is considered one of the best sci-fi books only by people who don't read sci-fi.

Not really recent but I'd recommend Blue Remembered Earth by Alastair Reynolds (but I'm partial to Reynolds after the Revelation Space series and House of Suns) or if you like military sci-fi Marko Kloos' Frontline series.

Children of Time (Adrian Tchaikovsky), The Expanse (James S. A. Corey), Broken Earth (N. K. Jemisin), Locked Tomb (Tamsyn Muir), A Memory Called Empire (Arkady Martine), Murderbot (Martha Wells), The Light Brigade (Kameron Hurley), The Wayfarers series (Becky Chambers), and The Calculating Stars (Mary Robinette Kowal) are some of my favorites. Brandon Sanderson’s Skyward series is also worth a read.

Mickey 7: People try to colonize an alien planet and the main character's job is to do all the very dangerous tasks. When he dies, his body is cloned and his memories are copied.

It looks like there is a movie in the works called "Mickey 17".

Only recent in relation to the classics, but I really enjoyed the following (the years are approximate). There are others, but I've listed these ones specifically because those others have already been recommended elsewhere in the thread whereas these may get missed.

- Adam Roberts: New Model Army (2010?)

- Hiroshi Sakurazaka: All You Need is Kill (2005?)

- Mike Resnick: The Dark Lady (2015?)

- KC Alexander: Necrotech (2015?)

- Gary Gibson: Stealing Light, Nova War, and Empire of Light (2013?)

- Linda Nagata: The Last Good Man (2015?)

Children of time, the expanse series, project hail Mary, the Martian. Almost all of these were written within the last 10 years.

Some good "modern" sci fi off the top of my head:

Adrian Tchaikovsky's children of time series, as well as his terrible worlds novelas

Anne leckie's ancillary justice series

Martha Wells Murderbot diaries

Andy Weir's project hail mary

John scalzi's old man's war trilogy (technically more than a trilogy, but they fall off after the first 3)

Maybe look at something like the Locus list of 2023 books. SF is such a broad genre that you are better off finding reviewers or other sources who you can use to guess at what you might like.

Dennis Taylor's "Bobiverse" series. Also Daniel Suarez's books - "Delta V" for the start. Devon Eriksen "Theft of fire" - this one is a bit raw and can offend some people.

These books take into account recent developments and events so they don't sound anachronistic like some of sci-fi classics. Maybe they'll lose that appeal in few decades and will be harder to read for our grandchildren, but I do enjoy all the cultural references from my time.
