No original plot. The same endlessly repeated storyline. Such a shame - each book seemed to echo the last more and more until this last one ended up with no originality at all.
It makes me wonder if the author even wrote this book herself, or rather editor(s) at her publishing house drew out, repeated and retold everything that had occurred already in the previous books. The 'Mother's Song' itself must have been repeated 10 times in this last book alone.
That having been said, the first three books will forever stand out as some of the best fiction I've ever read.
