Negative Positive
Title: different but good
Review: The 4th book is 15 years later, and considering the circumstances of this story, a different feeling is inevitable. Less of the ninja stuff (though still enough to make you smile) though still plenty of intrigue. If you liked the rest of the series, give it a chance. I found that the author introduces a new level of depth to the story by touching on more esoteric, philosophical, and humanistic subject matter.
Is the review positive or negative?
