My Dark Age adventure, Shieldwall: Barbarians! is Young Adult, meaning, in this case, Sharpe or Conan but without the shagging, and with slightly more moral compass - really you can read it as being "in the tradition of" Harold Lamb and the Pulpmeisters of Yore and ignore the YA tag. When I wrote it, I had in my head "Robert E Howard does Rosemary Sutcliff (but not that way (though they would have made a lovely couple))".
It's also an old-school young officer story, albeit with a barbarian prince as the protagonist, and it's set in the Dark Ages during Attila's invasion of Europe.
All this seemed like a good idea at the time.
