GOOD RULE OF THUMB.

If you happen to see a book in the library or at a bookstore and it has as its author James Patterson and somebody else, you can be confident it was written by the somebody else. James Patterson is a book whore. He has found it very profitable to slap his name on the book of unknown authors giving gullible readers an incentive to buy.  Publishers realize it's a scam, but the publishing industry is a huge scam, quick to promote a person as the author of a novel, how-to, or children's book who had nothing to do with it. Most celebrities never write the books that claim to be their work. If you wander through Barnes and Noble, you will soon realize that 74- year-old James Patterson couldn't possible write all those books.
