This is the book that I have been waiting for and I managed to finish it. So this book basically about the existance art of ninja and sharp mind can be part of women's strength. All I can say is that Mariko still need to be develop into more strong character. To me, I still haven't see any of main character's action can be exemplery. hopefully, sequel can show more of Mariko and not just being a greeny. Show how capablel she is as a ninja.
