No, As far as buying goes, I stated I would Not be buying any of the five and five until the last one comes out. I will buy that, and, if it makes me want to know what happened previously, then I will work my way back. Nor was I interested in works outside the main character stream, e.g. Jethri, or Jethro, or whatever the BoT protagonist is named, or the recent one about the hidden people in Surebleak.
And as far as reading goes, I regularly re-read the many Liaden books I have--the short story collections and the novels up to Ghost Ship ( it and the subsequent ones I have I do not read again). It is a universe with many great characters. I would be thrilled to buy Liaden books that were about mainstream characters--the early careers of Liz or Nateesa, or the scout careers of Daav or Val Con, or anything about Chia (sp. The Delm before Daav), or the trading career of Shan, or more stories of Pat Rin the gambler, or, or, or. What I am not interested in reading about is Theo the Brat, or stories about new characters who have popped up, e.g. Diglon the Rifle).
And I read your blog every day, which, of course, has Liaden stuff in it regularly.
