direction on soldier son seriees

[Nuytsia]

Hi there oldredr!

You can read Soldier Son trilogy at any time, as it doesn't relate to any of the other books.
I guess it depends how eager you are to read more about the world of Farseer trilogy. If you are then I'd read Liveships next (although the characters are different it's the same world and there is some crossover).
I'd definitely read Liveships before Tawny Man trilogy if I were you.
