Josh, that is true.
His wife (and editor since page one) has all the notes, the whole thing has been scripted for quite some time. And a few weeks ago RJ sat her and Cousin/Brother Wilson down for an all day Storytelling session, laying out EVERYTHING (Wish we had video of that!)
Harriet had edited RJ's work for 20 years and is a poet and author in her own right. She can capture his voice and finish book 12. Time is the only question. For her I hope the work will give her closure, otherwise the whole effort may prove too painful to bare. No one is rushing her to get it done, the whole fan community is being very supportive.
There are plans for an international Wake on his birthday (Oct 17th) Fans are rushing to make arrangements all over the world.
Any interest in joining the game?
