Like you i have read various ganres in my life and the biggest disappointment is the unfinished book series by George RR Martin...
I love thrillers, so I eagerly await every new book written by Ju Nesbe.
Lately I've been reading local authors, currently the life story of the actor Žarko Laušević "Sve prođe, pa i doživotna (Everything passes, even life imprisonment)", who unfortunately passed away too soon.
And perhaps the best book in the last couple of years, the local author Đorđe Labović "SEMPER IDEM".
My recommendation
https://www.amazon.com/SEMPER-IDEM/dp/8652123152
It's good support local writers, and as for RR Martin...damn that man! 🤪
