This series seems to be losing some of it's spirit. It just seemed to go on for a bit too long and felt almost like an excercise in writing a series rather than a serious inclusion in the series.
The fight between the magi and the jousters and the other magic users intensifies and starts to get serious. More and more children are turning up dead or drained. The Magi are planning to do more damage.

It is a problem sometimes with Mercedes Lackey that her bad guys rarely seem to have shades of grey involved.
