There’s some decent world building and the general story is alright but beyond that, Reincarnation is disappointing. Characters are all one dimensional. The protagonist never faces any real struggles. He’s supposed to be very intelligent but this is handled by making any opposition rather simple minded, having people react in wonder at simple plans, and ignoring huge gaps in his logic at times. Hypocrisy abounds (traitors to the clan are bad but robbing the clan at every opportunity good?) and torture presented as good. The concept of Jim having to deal with challenges of being young again was interesting but ignored even though it is supposedly a core part of the story. Great narration makes the book at least enjoyable but hardly anything great.
