I really enjoyed The Hyperion Cantos, and the first few Dune books I read a long time ago (may reread these now). Can anyone recommend some other books (or series) along these lines? Huge stories on an epic scale, space battles, cool future tech, etc.
I would recommend the Red Rising series by Pierce Brown. Every book takes place on a different planet with an amazing amount of character building and detail in the plot.
Did you finish book 5? That one was a slog for me, and I enjoyed most of the rest (even if book 3 showed much of the strain of finishing the first trilogy, I never felt the pacing slip as much).
