I'm a casual Star Wars fan at best, so the first third of the book is bewildering. Not because it's introducing a whole new cast of characters -- and the circumstances of the opening third of the book do serve that function well -- but I'm not conversant in which species is which or what the properties of Tibanna gas are, and occasionally I needed to remind myself that Star Wars is not hard science-fiction. (In the back of my mind, I was screaming, "What about the delta-v? What about the delta-v!")
The set-up -- on the eve of the opening a space station (the Starflight Beacon) that will serve as an outpost for Republic law and values at the edge of the frontier (think Deep Space Nine or Babylon 5), an accident in hyperspace causes a starship to break apart and its debris, moving at near-light velocities when it emerges from hyperspace, threatens several worlds in the Outer Rim. The Jedi respond to a planetary distress call and, in true Star Trek competence porn fashion, deal with the problem. Through this, we are introduced to a whole lot of Jedi characters -- who they are, what their power sets are, how the react under pressure, etc. We see some Jedi on ships, we see Jedi on away teams, we see Jedi working with the locals, etc.
My references to Star Trek aren't misplaced here; while Picard would have solved the problem with tech to implement the strategy he worked out in his head and with his crew, the Jedi solve it with the Force to do the same thing -- they think, they collaborate, they put it into action. The Jedi, at least in the first third of the book, are the Starfleet to the Republic's Federation -- the goers and doers, an inspiration and a light in the galaxy.
A third of the way into the book, things change. We meet the Nihil -- the overarching threat, as I understand it -- sort of. The action shifts to Coruscant. Now the clock is ticking -- will Babylon 5... I mean, Starlight Beacon, begin operations on time?
Soule's writing is fine, though the line from Amadeus -- "too many notes" -- would not be amiss. I'm not completely gripped by this.
