I put her in the same category as many other "popular at the moment" writers -- the books sold well, they were not bad, but certainly nothing amazing, and now are not anywhere near as popular as they once were.
When I read the first three Dragonrider books during their heyday I came with this impression -- dragons. caves, Thread, klah, people talking, more Thread, a bad time-loop scenario, end of story. I couldn't remember the name (much less the personality) of a single individual in the series and cared even less.
Later on I discovered the Harper Hall series -- they are actually much better, partially because I believe the McAffrey is a much better Young Adult writer (this is not a put down at all -- this is a very difficult age range to write for!) and partially because there was more of a sense of love of characters, rather than scurrying to get a plot in order, in the books.
Just an opinion, for what it's worth.
