Damn, now I MUST get my hands on it. I'm into volume 3 and I really think you could demultiply every volume and still get a gripping story. Hitchcock said "the badder the villain, the better the story", and you've certainly very good/bad villains here.
Please consider a review of what you have read, placed on Amazon and/or here on FR if you are so inclined. Word of mouth is my best friend with the series.
Either way, thanks again. Glad you are enjoying the books.
