Rewriting or Re Editing?

The thing that the editor can do that the writer can no longer do, as we can see it fresh write. So i think you are hiring some one to get that fresh pair of eyes that you just cannot have yourself any longer. I approach it especially if this is my first read, i've obviously never stepped into the manuscript before. And so whether it hangs together, again, i guess this goes back to what's human. What's human about the editing a is, how does this thing hang together and progress in your mind from beginning to end? Whatever of book is, itsjorny for the reader.
