I just finished the book, and it was wonderful! To those of you who disagree, let's get one thing straight: this book wasnt intended to outline a huge adventure and turning point in the star wars timeline--that's what episode 2 is for--it was written to further character personalities and relationships. And further this it did beautifully!
First, I really liked that we see the Jedi Masters, Mace especially, as people.
I enjoyed very much the look at Obi-Wan and Anakin's relationship as master/apprentice and friend/friend alike. I also loved the personal struggles that we see each one go through--it shows they're very alive and very real, such as Obi-Wan's love for Anakin and his lonliness for Qui-gon, and Anakin's battle with himself and the voice he hears and the dreams he dreams. It's also interesting to observe the great power that he cannot yet control.
The appearance of Tarkin was very interesting as well. It is nice to see him as a young man, but he is little changed from when we see him in A New Hope. I thought it ironic that he makes the same mistake of underestimating his enemy, only this time it did not lead him to death. I thought it was a little confusing in the book when it says he came up with the initial idea for the death star, but if you remember, so did the scientists in the maw installation.
This book also does some major foreshadowing and linking. It hints, or more like shouts, that the world of Zonama Sekot has been attacked by the Yuuzhan Vong. From this, and the second Dark Tide novel, we gather that the Vong have been planning to attack for decades...I wonder what would have happened if they had striked the Old Republic, or the Empire... And speaking of the Empire, Tarkin constantly hints that a great change in power and ways of the government are about to take place in the future. He also hints at what we know as the Empire's ways, telling Sienar that humans are the race of the future and so on.
In my opinion, the book also links Anakin Skywalker with his grandson, Anakin Solo. Notice how they both are incredibly strong in the Force, have a knack for dealing with machines, and want adventure and excitement.
Overall, this was a wonderful book that bridged the gap between the first two episodes of the Star Wars prequels perfectly, and provides exactly what Episode 1 lacked the most--character developement.
