Though I've known Luke since he was a teen I don't keep too much in the loop when it comes to the things he puts out. I do know that he's heavily influences by at least one key source who is known to do the same sort of thing; just readjusting and adding to something already published. Sadly, it is a loop many of us get into when we write. My Easy Reading manuscript has seen two major re-writes and re-releases since it's original introduction and I'm in the process of re-doing it now so as to up-date it as well as make some adjustments (corrections)... One of my favorite writers in the Occult world pointed out in a new edition release of his first book "REAL MAGIC", that it is the onus of every author to live with the words he's put into print only to see how incomplete and imperfect they are later.
I know that it could seem unfair a times, but I also understand it from the perspective of the contributor and the frustrations we tend to go through; especially when you're both, creative and a perfectionist.
