General book recommendations!

I don't know what to read next and I'm looking for recommendations!

I tend towards fantasy/sci-fi as genres but love a good mystery, so would be up for a mystery of any genre.

I started reading again a couple of years ago and read mostly romantasy, but I've gone off of that (wouldn't mind at all of there's romance in the novel, but I just don't want it to be the entire plot line). I tried epic fantasy and have read quite a bit of Brandon Sanderson, but I find it a bit boring as I find that nothing happens for large chunks of the books.

Last year I read the Red Rising saga and loved it! Even though it's a series and long, I felt like there was always something happening.

I've just finished Project Hail Mary and adored it. Loved that it was fast paced, that there was a mystery to solve, and loved the characters.

So I guess in summary, I'm looking for something fast paced/always feels like there's something happening, with engaging characters, a mystery to solve or a problem to solve? Ideally in the fantasy/sci fi genre, but nothing too heavy!

Not too much to ask, right?
