I've collected several of the Destroyer series and the Horseclans books, but it's more about the hunt through used book stores than the reading.
Are they still (ghost)writing Destroyer? I know the number of books in the series is in the triple digits.
EDIT: I looked it up. The highest I found at Amazon was #134 and ranked a solid 1(one) star in reader reviews.
Hey, I never said they were great literature.
The comic book series, on the other hand, was great.
