If you enjoy SW books you need to read this. The Plagueis stuff was interesting. The Palpatine stuff is fascinating. Getting the back story and "behind closed doors" stuff on him leading up to and into The Phantom Menace.
And then all the interesting things about and leading up to the roles of Jedi Master Dooku, Padme, Sifo Dyas, Nute Gunray, San Hill, Valorum, Darth Maul, Qui Gon, Obi Wan, and the list goes on.
Fun to read a SW book again that I really enjoyed.
