Fifteen-year-old Maya Donovan is trying to make the best of her new life in Tokyo, but it hasn't been easy. Lately, mythical creatures seem to be walking out of the pages of Japanese folklore right into Maya's life....and they haven't been friendly. Maya is savagely attacked by one of the mythical creatures. She narrowly survives thanks to a pair of sword-wielding samurai who come to her aid. Now Maya has only three days before the creature returns. And this time it has a taste for Maya. If she's going to survive, she'll need to enlist help. The samurai are Maya's best chance for survival, but will these mysterious warriors be able to help her in time? Can they be trusted? Or do they have an agenda of their own?
