Which book has Luke turning to the dark side?

I must have missed it, but which book has the story of Luke turning to the dark side? I've read from Darth Bane to some of the New Jedi Order, and unless there is a book not in my collection, I swear there is no book with this story.

Thanks in advance.

Dark Empire.

Oh, Ok. So it wasn't a novel? It was a Dark Horse graphic novel? That explains it. I haven't read any of the graphic novels, I barely have time to fit in the novels.

Thanks!

Thats a great graphic novel

Indeed, Luke's fall to the Dark Side is featured in the Dark Empire graphic novel.
