I just found out a year or two ago that there was a third Covenant series. If I recall, the second series came to a good closure that would need to be undone in order to write more. Is it worth it to rip up that closure and read the last series? From your comments, you don't seem particularly happy with them, but do the wrap up the whole series in a overwhelmingly well done way worth discarding the closure at the end of the second trilogy?
It's okay. It is not horrible.
The Best book in the entire third quadralogy (it is 4 books, not 3) is the first one.
The Second one is the worst book, and one that you just want to get mad at some characters for stupid choices (I hate it when characters in books make blatant and obviously stupid choices).
The third book is okay.
The fourth book is okay, but I dislike the ending. I found it a cheap way out. It is a happy ending, but cheap. If I told you why it would be a massive spoiler, but I thought it was CHEAP. The author wrote themselves into a corner and basically couldn't find a good way to get out of it so made the ending they did, at least that's what it seemed to me.
The High mark is the Second Chronicles. It's all downhill from there.
That doesn't mean the third set is bad, just gradually declining in how good it is from the peak of the 2nd Chronicles. It is still enjoyable to read though (It's still Donaldson writing).
There are some things that are good and worth reading in it, and some things which if you analyze it more than just a fun read really will strike you in many ways (such as a direct analogy in some ways at the end to the Father, the Son, and the Holy Ghost...though male/female may be somewhat interchangeable in that reading).
