That is an interesting video about the spooky books, I heard about HEX from one of my colleagues, she was very excited about the story and as it is once you start something like horror or mystery you just get so much into it that you can’t really stopped. She liked the fact that there is a history of past as the witch lived very long ago and it is connected to present when the inhabitants of that Black Spring tried to chase the witch with mobile App, but also that the people once they are there could not leave the town for a long time. Anyway, she was impressed and advised me to read it and now I see that you also reading the same book. As to the Japanese it is a difficult language, but if you have chosen it just go ahead and try your best. Good luck!
