Do all the WWE books have the same ghost writer?

[Johnny S.]

The voice in all the books almost sounds like the same person. Except for mankind's book which has a different voice.
If you don't read and don't know what I mean about voice in a book, the sentance structure is very simular in hogan's book and flair's book. The paragraphs are put together in almost the same way. In places, you could almost forget who's book you are reading.
