Killing November

My name is November Edley. One day I woke up in an ancient castle on the edge of the world. There is no electricity or communication with the outside world, and escaping is almost impossible.

This is now my new school. Here they teach disinformation, martial arts, poison science, and strategy. Instead of friends, there are only lurking enemies, instead of lessons — deadly trials. 

All violations are punished according to the principle of «an eye for an eye». The only one who seems friendly is a mysterious guy named Ash.

He reads me like an open book, but he does not rush to reveal his secrets, nor to tell about the secret society to which I have belonged since birth.

Everything gets complicated when one of the students dies and suspicion falls on me. Will I be able to find the real killer to avoid a death sentence?
