I really enjoyed this nobel. Amazing!! I have done "Ohenro" visit and pray around of Kukai Temples of 88 in Shikoku, Japan long time ago. After reading this mysteriou story, I would like to visit again.

This is the most breathtaking story by master of Ninja, Sho Kosugi. I am now living in the island “Shikoku” Japan where the story is developed. It is surprising to know his deep understanding about the historical background and blending that into modern adventure. Highly recommended for those curious about oriental mystery.
