I think most of the after prequel books were uncannonized.
I just hope they don't use any material from that terrible aftermath book. One of the only books I've started and never finished.
A lot of the old legacy star wars books weren't great, but I don't think Lucas film has set the bar too high with these new books.
I wouldn't normally be too afraid of them using material from books, but they seem to want the universes more tightly connected now.
I wonder if Favreau's movies will do any battle of jaku stuff. I could Google the timeline but I'm way too tired for that.
All the older / pre-Disney acquisition books were de-cannonized but I thought the more recent books were ok ... even still, even if not part of cannon, feels like it's been covered before
funnily I enjoyed the Aftermath trilogy (not the best written books but I thought some of the storyline was interesting and covers the battle of Jakku and sets the stage a bit for at least the setting of the Force Awakens
The Battle of Jakku took place in the year 5 ABY, so only like a year or so after Jedi - so if he is going 10 years after that, that would be like 13-15 ABY or so - when not much happen (other than Rey being born in 15 ABY) - so would be new stories
Here is a decent reference that I use when determining what new stuff to add to my reading/watching list

On
April 25,
2014, after a year of ownership by the Walt Disney Company, a
StarWars.com press release confirmed that the films of the
sequel trilogy would not adhere to the post–
Return of the Jedi Expanded Universe,
[12] with further comments from
LucasBooks Senior Editor
Jennifer Heddle confirming that the EU as a whole is no longer considered canon. The EU has been re-termed "Legends," with related publications remaining in print under that banner.
Since then, the only previously published material still considered canon are the six
original trilogy/
prequel trilogy films, the
Star Wars: The Clone Wars television series and
film, and the stand-alone
Dark Horse Comics arc
Star Wars: Darth Maul—Son of Dathomir; which was based on unproduced scripts from
The Clone Wars TV series.
[1] Most material published after April 25—such as the
Star Wars Rebels TV series along with all Marvel Star Wars comic books and novels beginning with
A New Dawn—is also considered part of the new canon, on account of the creation of the
Lucasfilm Story Group, which currently oversees continuity as a whole. Characters under the Legends banner are still available for use as needed, even if events concerning them are no longer canon.
Exceptions
The following material, although released after April 25, 2014, is not considered canon:
