An excerpt from that Aftermath book (that's supposed to start to link Jedi to Awakens) was released. http://www.ew.com/article/2015/07/16/star-wars-exclusive-actual-opening-aftermath-reveals-tragic-violent-uprising
Aside from being poorly written, it's interesting that they decide to kick off the film with a scene from SE Jedi. Somewhat satisfying, at least, to see the dumb little parade that Lucas added goes to shit pretty much the moment that shot ends, though.
I don't think I'll really be brought in by this piece of drama. But I'll probably read the novel for more glimpses of the post Jedi empire, as it's now being imagined, trying to hold itself together.
