I do believe the novel info is outdated as he's currently working on a script. As per recent info regarding the man himself(see StarNewsOnline article/interview) and I quote "He also hasnít completely ditched his other passion. Heís in the middle of writing a script, even though itís slow-going because he only writes during his free time from the show. He says he doesnít want to take any time away from ďOne Tree Hill.Ē"
Thanks for posting!
