Here's the summary from amazon:
Sixteen-year-old Kara Foster is an outsider in Japan, but is doing her best to fit at the private school where her father is teaching English for the year. Fortunately she’s befriended by Sakura, a fellow outsider struggling to make sense of her sister’s unsolved murder some months ago. No one seems to care about the beautiful girl who was so brutally murdered, and the other students go on as if nothing has happened. Unfortunately, the calm doesn’t last for long. Kara begins to have nightmares, and soon other students in the school turn up dead, viciously attacked by someone . . . or something. Is Sakura getting back at those she thinks are responsible for her sister’s death? Or has her dead sister come back to take revenge for herself?
Sounds creepy! I am always drawn to stories about foreigners in Japan (since I was one for 9 months) and I hear this one has a very special cat in it too...
