Query: Good book. I'd recommend picking it up.

Pretty good book. I was suprised that I enjoyed it to be honest. It picks up after revenge of the sith and shows anakin becoming vader in mind body and soul. The book would have been better if the characters he was fighting against were in any way interesting. They are just shallow characters to get pimped slaped by vader.
