Tokyo Natt (Tokyo Night)

Instead of just reading the authors I know, I am trying to pick books more at random and just finished a very good book, Tokyo Natt (Tokyo Night). It is about a young woman that moves back to Tokyo where she is born (she is Swedish) and her struggles to find her self. It is a story about the life in Japan, parties, drugs and men and everything that comes with that (happiness, sadness, love).
