This is not exactly a review, but I just wanted to say that often times when a series stretches as long as this one has, the quality of the writing can begin to wane.
Thankfully, that is not so with this series.
I've not rated any of these books lower than a 4.
Also...a big, big YAY for Paul Gibson having more page time (he's one of my favorite characters), as well as the new characters that were introduced. I look forward to hopefully seeing more of them in the future.
