Ok, a few quick books I'll mention that I'm pretty sure haven't been discussed yet.

One is a book that just came out recently, Unconquerable Sun by Kate Elliott. Its a bit out of my wheelhouse as I prefer fantasy to SF generally, but the premise of a retelling of Alexander the Great's story in a space opera setting seemed intriguing and I really like some of Elliott's earlier stuff.

Anyway, I really enjoyed the book so if any of that sounds interesting I would recommend it. One potential trigger warning I guess if it bothers you: she gender flips the family. By that I mean the main character Sun is a girl (based on Alexander), her mother Eirene (based on Philip), and her father Joao (based on Olympia). Didn't really bother me, but I figured I should mention it. One last thing, this looks to be a trilogy with the next two titles already listed, but you know how that goes.

Secondly, there are two trilogies by K.J. Taylor that might be worthwhile. The first, called the Fallen Moon trilogy, follows a main character and his griffin as they set about freeing the guy's people. Its pretty dark and violent, but I would strongly recommend it for pretty much any fantasy enthusiast. The second trilogy, called the Risen Sun trilogy, follows the main character's daughter. This one didn't work for me as well, but it may for others. I have a pretty hard time with any series that jumps generations. I don't like going from one person to their extended family, just a personal preference. But if that doesn't bother you, it could be a good read.

Lastly, I just want to mention one of my personal favorites by Jennifer Fallon, the Second Sons trilogy. It was her first stuff written a while back, but I love it and reread it probably once a year at least. Its a bit different in that it follows a character who isn't really a warrior or magic-user (or both) like most stories, he is a genius when it comes to mathematics and science. I enjoyed that different perspective and the Machiavellian politics that the story goes into. May not be for everyone though. She also has a number of other fantasy books but I found diminishing returns and eventually stopped reading her later stuff so no idea about those.

Anyway my 2 cents for now.
