Turns out that didn't work out so well... While Pet worked as a stand-alone story, the others did not.
Luckily I picked at random the best one to start with, Green but for a Season. It was about a character named Jord and his time in the Prince's Guard. I'm sure, if read after the book that plotline was part of, this story would have been a lot of fun, but I don't remember much at all about the series, so for me this short story was about people I didn't know and a conflict I could barely recall at all. I finished it, and it was mildly interesting, but I can't say I enjoyed it.
The other two short stories, The Summer Palace and The Adventures of Charls, were intended as the trilogy's real ending. For reasons I can't recall (deadlines with her contract?) the author had ended the third book badly -- basically she *didn't* end it, just ran out of time to finish it. So, without remembering the last book at all (beyond that I hadn't enjoyed it), these stories were meaningless to me. I got about halfway through one and didn't bother starting the other.
If I read other short stories this year, I'll toss them into Book #9 to try to bring that up to a full book's worth of reading.
Currently reading: Man-Kzin Wars VI. No, I haven't read books 1-5, but as these are collections of stories set in that universe, they don't need to be read in order. This is the one I just happen to have.
