Query: A shocking betrayal

As another reviewer noted, this book is too long by at least 200 pages, but most loyal readers wouldn't mind that.What loyal readers will mind is that the author deals with a major supporting character in an unexpected, cruel and random way that winds up being completely unjustified by the rest of the plot. I've read this series from the beginning, but I won't be reading the next one.
