Journey into Darkness (ISBN 1-4165-0747-7) is a 2005 novel written by Michael Chiappetta and David Stern and published by Pocket Books for World Wrestling Entertainment. The book is a fictionalized history of the professional wrestling character Kane, portrayed by Glenn Jacobs. The story ties together pieces of the real life Glenn Jacobs with Kane, such as giving the character the name Glen Jacob Callaway, and the idea that he took the name 'Kane' from his mother's maiden name, as she was referred to several times as 'Suzanna Kane'. The story also deals very sparingly with the character of The Undertaker, Kane's storyline brother. This was the first WWE fiction novel, the second being Big Apple Take Down.
