Really great book. The writing is done well. The story is fantastic and has a decent flow to it. The politics are a bit confusing to me, but I don't feel like reading it again would be hard, because I actually enjoyed it. The mysteries of the dark side are tantalizing.
This book is the best Star Wars book I have ever read. If you want a book from a Sith perspective this is it. It answers many questions, but also leaves some up to you to decide. If you are going to see Episode I in 3D read this first. It will make it more meaningful to you.
