Newer stuff?
David Weber...pretty much anything by him including the Honor Harrington series and its spin offs, the Safehold series (one of my favorites), Empire of man series, and so on...
John Ringo’s “Black Tide Rising” series fascinated me some how, I’m not sure why. I would definitely recommend it to anyone interested in post apocalyptic fiction. His Posleen War series was also very good, though some of the spin-offs got a bit tedious. His Council Wars series was definitely a different spin on a forced return to pre-industrial age society, and lastly his “Paladin of Shadows” series quite rightly sparked the “Oh John Ringo, No!” meme a few years ago, but I still liked them ;)
If you like Weber you’ll like David Drake as well. I prefer Drake to Weber. Much the same stuff.
I read a bunch of the Posleen series and enjoyed it but also found out juvenile in a sense.
Agreed about Weber. Some of his latest Harrington book have lots of words but do not really advance the plot much. They could have been distilled down to a good sized short story and nothing would have really been lost.
Gotta say though that Everything I’ve read by Ring has rockdd. The Aldenata series is most excellent on every level.
