All 4 books could have been written as 1 book
I read all 4 books in this series. It was interesting, but there was too much repetition throughout each book and each subsequent book gave repeated extended history from the previous books, which was really unnecessary. All 4 books could have been written as 1 book which would havce saved all the repetitious history. If reading the books one after the other as I did, it made for quite a boring book. I skipped quite a bit in the final 2 books. I can understand why the publisher discontinued this book. Well-written, but disappointing.
