I am one of the community editors for this book. My name is listed in the acknowledgments.
First let me say that the book is awesome. It's got a great plot, great characters, and it pulls you in. A few times I was late to work by a few minutes because I just couldn't put the book down until I finished the chapter I was reading. I highly recommend it.
Now, let me explain how I helped edit the book. I can't speak for the other editors, but this is how I got involved. I decided I was going to read the book, so I downloaded it and started reading. I find that I'm pretty good at finding typos and grammatical errors in books. I find them in books that are published by the big publishers & authors all the time. I usually find at least one or two mistakes in every book I read. When I was reading thicker than blood I just started keeping track of everything that I knew was misspelled or grammatically incorrect and everything that I was unsure of as well. When I had finished the book I found that I had nearly 200 edits, so I sent them over to the author. He was very grateful and a few months later he sent me a printed copy of his book.
So, the 'nd' doesn't really apply because I never made a derivative work, I just sent him a patch that was human-readable-only. The changes that I made are so small that copyright doesn't apply to my changes. I mean, I would assign him the copyright if it did matter, but such a small change would not trigger copyright. If I had rewritten a few paragraphs or added any real substance it may have, but fixing typos and making sure apostrophes are placed correctly does not deserve any attention from copyright. These are the contributions that I made and I can not speak for other editors.
Again, I can't recommend the book enough. I can't wait for the sequel.
