Not an "authorized" sequel, but as you can see it IS a SEQUEL - and not only that, but also positively a sequel of THE ORIGINAL CLASSIC. It was written by one Dacre Stoker who is an authentic great-grand nephew of Bram Stoker.
But hell, so am I. Well, no, but I think I am a great-grand nephew of Bob Dole. Seriously. It doesn't make me a Senator.
Prior to all of this mockery I did read two pages, and they are really bad. Mr. Stoker has a co-writer, too, Mr. Ian Holt, who at least has credit as a screenwriter. Mr. Stoker is a high school gym teacher.
