spoiler discussion of Outremer

[julesjones]

I did eventually realise that my problem with writing an overview of the Outremer series was partly that I kept wanting to talk about stuff that was a big fat spoiler. So I'm going to make two posts -- this one as a placeholder so that I can stick spoiler discussion in a comment later, where it won't be seen by those who don't want to read spoilers, and a separate post with a summary review of the series.
