For some reason, Amazon has posted identical reviews for both Vol. 10 and Vol. 13 of this series.
The previous reviewer has indicated that this is misleading, which is correct. However, it is not correct that the reviewers are doing the misleading, since all reviews posted for both Vol. 10 and Vol. 13 are showing up in both places, which is Amazon's error.
