No, the two Piercing the darkness and Present darkness are the ones this poster is talking about. Hangman is about a mystery in a school where people think that there is a ghost killing kids. The Visitor is about a man who comes to a town and claims he is God (at least that is what I think it is...LOL) His books are different from each other...I don't think that the two first books were that bad tho. It has been a real eye opener for me and other people!
