I'm always reading something, usually multiple books at a time.
I read/listened to each of these books individually and did write-ups on each one, with the intention of writing a review covering the entire series. This is that review.
My individual write-ups can be accessed at the following links:
Note: While I avoided spoilers for each book, I did refer to events of earlier books once I got past the first.
The remainder of this review will be placed behind spoiler tags. Spoilers for all four books follow.
