Query: this book was excellent

I thought this book by Mick Foley was excellent. However, I saw him on several interviews and he stated that he wrote it all himself on 750 sheets of notebook paper, there were no "ghost" writers. However, I am now finding out that he had not only a ghost writer, but that there were "2" ghost writers. Please respond asap. Thank you, Renee' W. Byrd
