I read the first book in this sequence in the 1970s and ever since have eagerly awaited each new book. The long wait between books never mattered as I relished the fact that unlike many fantasy authors KK puts plenty of care and attention into each volume. Unfortunately at some point after the last trilogy in the mid 90s things started to go downhill. The books remain as well-written as always, but for some reason KK has forgotten to put a story in. The Brides of King Kelson appeared to be just an exercise in filling a few hundred pages with stuff, and so does this one.
There is no obvious main character, no main thrust to a plot, no plot in fact for most of the way. It's not a bad read as the author can still write interesting passages, but to me it appears that the weight of all history created for this series is now stifling the stories that can be written. Some people must die, other mustn't, and for no good reason other than the history in the other books say so. So the 'story' here is filled with characters falling off horses and taking a while to die, for reasons nothing to do with any story, then having other characters report that someone has fallen off their horse and may die, followed by them telling other people about the unfortunate faller... This report then gets passed from person to person in a style that feels like a soap opera where all that ever happens is us getting to see everyone's reaction to the news that someone has fallen off a horse.
Once the person has died we then move on to someone else randomly getting chucked down a well or falling over and that news getting reported to all and sundry. In short very, very low on story and character, and to be read for completeness only. Better still re-read one of the earlier trilogies.
