I didn't realize it when I started listening to this, but this is basically the prequel book to episode 2. The title refers to the gathering storm that is the start of the separatist movement that leads to the clone wars beginning in Attack of the Clones. It doesn't end immediately before the movie begins (at least it didn't sound like it), but close enough that those events would be soon. And that's why the four jedi are sent to Ansion, to try to help stop those that want the planet to leave the Republic. For those that like ship battles or the like, it's not going to be the most exciting book out there, but it is interesting to see how the saga as a whole continues on with what we don't see on screen.
