The second book of the Corellian trilogy is even slower than the first.
Basically, I contend that this trilogy should have been one single book. The author spends way too much time bogged down in describing minutiae that hardly advances the plot and which can and should be summed up with a simple synopsis: "the craft spiraled out of control and crashed to the surface," for example, would cut out at least 100 pages from this trilogy.
Tendra Risant's storyline here is completely unfulfilled. Indeed, she has her own passage of tedious minutiae that doesn't much advance the plot but which sure fills up a lot of space.
What then is the plot? Basically, Han and family go on a ridiculous, un-escorted vacation to the Corellian system and Han and Leia get separately captured while the kids, Chewbacca, and minor characters discover a planetary repulsor that a seemingly unified system-wide insurgency are trying to find and wield for who knows what. Luke and Lando ally with the Bakurans and harness their fleet in order to solve the problem.
The main plot is mostly good and would make a Star Wars book just about as good as Truce at Bakura or The Courtship of Princess Leia, but, instead, the book was unnecessarily stretched out into a trilogy. The plot wasn't expanded, but the number of pages was. That simply means that a good deal of filler has to be added, such as, like I mentioned above, spending dozens of pages describing things that could be expressed so much better with a little condensing.
I don't know about you, but I don't consider Star Wars books to be great literature: I read these books to find out what was the original pre-Disney canon story of what happened after RoTJ, and therefore what I am most interested in is the plot. I want to know what is the mission, why is it the mission, how does it connect to the general narrative of the post-RoTJ timeline, and what happens next. I don't have time to beat around the plot bush and focus on things that are irrelevant.
If was not Mr Allen's decision to make this a trilogy and he had to make due with what he had, then I guess he did the best he could with the material he was given, and the filler was necessary. But if it was his idea to create an unnecessary trilogy out of what should have been one book, then shame on him and whoever did the editing!
