Will Wight the Cradle series. Kinda silly but definitely fun.
Julian May the Pleiocene Saga. One of my favorites. Written in the 90s so… Not current but still good.
Mark Lawrence - enjoying most of his books. The Impossible Times trilogy is certainly fun.
Richard Morgan used to be one of my favorites until Netflix ruined the Takeshi Kovacs books.
Again with the older authors: Philip K. Dick (everything). Vonnegut (most, but not the last few books) Gene Wolfe books of the new sun cycle, 12 books if you consider the books of the long sun/short sun. Kinda surreal but hypnotic and addicting. Strugatsky, Roadside Picnic. A classic. Ursula K. Leguin, most of her titles - not as easily read -as there is an emotional level that needs to be absorbed. The Books of Earthsea and the Dispossessed are absolute master level writing.
