I like reading books! Yesterday I read "Kokusyousyousetu" (黒笑小説) written by Keigo Higashino. He is one of famous writer in Japan. His book sometimes make a novel into a movie or drama. For example "Tegami", "Byakuyakou", "Ryuuseinokizuna", "Shinzannmono" and so on. He write good mystery!
"Kokusyousyousetu" is not mystery but you can enjoy black humor! It' very fun:) This book is short story. So you can easy to read it. And other his book is very good. But you don't like mystery I can't recommend them.
Please try it!! And enjoy reading☆
