So this has been optioned (for at least a second time actually - Book 6 or 7 has an author's note at the end that the series was optioned...and that book came out in about 2008) to be adapted into a movie, and I remember reading them in high school in about 2010.
But rereading them, I realized I don't remember any of it. Honestly, not a whit. It's not even "oh I remember bits and pieces", I think the one thing I remembered is that, well, there was a ranger and he had an apprentice.
I wonder how many of these I ended up reading eventually. Maybe up to Battle for Skandia? Well, now I read the first 10 (because there's both a sister series AND a sequel series AND mini stories and the continuity is a bit of a mess).
