I have read this so-called gospel and I have a copy of it bought from Higginbothoms. It is also available in the net. The one I have is a clear fake. It is blasphemous, right from the immaculate conception till the crucifixion. In fact I recommend it to be banned. To avoid others reading it, I bought all the copies that were available in the book shop. I am not sure whether it is the same they are talking about now.
