My review is up of Star Wars: Dawn of the Jedi: Into the Void by Tim Lebbon. It was fun, and like all Star Wars audiobooks, there's lots of noises outside of the narrator's voice. Some I've heard don't care for this, but I you'll hardly count me in their number.
The “Je’daii” have a mysterious society that does its own thing, which tends to be for the betterment of the universe, saying “may the force go with you.”... Also, they use the force and swords and have masters and apprentices. So it’s definitely an origin story and not just an exact replication of the jedi we know and love.
