Well, I watched the movie (A while ago)- and couldn't find the book. It is ah-mazing. I can't really say too much. It left me breathless. In this movie, InuYasha and the gang finally defeat Naraku and go their own ways.
Kagome (Who stays with InuYasha and Shippo) meets Hojo (Hojo's ancestor) and then gets kidnapped by the woman trapped in the mirror (Who broke free when Naraku went to heck). InuYasha goes to save her (and Hojo comes along with Shippo) and then Miroku and Sango miraculusly find their ways over there.
This movie is fulled with action-packed adventure and InuYasha and Kagome's FIRST KISS!!! EEEP! Also, Kohaku 'remembers' and Naraku comes back out of his back. Kohaku then dissapears with Naraku into... somewhere.
But don't forget, this is only movie two- and tons of episodes follow it, leading into InuYasha- The Final Act, episode... 14 came out... today... I think...
READ IT! WATCH IT! LOVE IT!
