They never went over that. I would like to know how the Emporer, Vader, and Jade meet. I think it would be an interesting recruitment. How does Vader except another force user being utilized by the Emporer. Or- Does Vader even know about Mara.
This could be a great book to tie things together. The Outbound Flight tied that event to his sequels. Now, he will have a Mara Jade story to bring everything else to closure.
You can tell he likes to make pre-prequel and pre-NJO novels. Even though Outbound Flight was a prequel novel, I believe that is his only attempt at confronting a young Anihkan.
R.I.P. to 'The Source' and 'MacCorp'
