In short, Memoirs of a Geisha is a fictional book about the life of Chiyo, who is sold to an okiya as a child to be raised to become a geisha. The story narrates Chiyo's (who becomes known as Sayuri later) story from the time she was sold to the okiya, and all through her life as a geisha and beyond that.
Memoirs of a Geisha is really well written. Arthur Golden made me believe that it was "really a memoir" because of the convincing way he wrote out the story. I thought I would perhaps be bored with the traditions that I had to read about so that I could be informed on all the details of the things geisha went through before becoming a geisha, and even after, but I found myself really interested.
It was slow the first 100 pages, but the pace sped up incredibly afterwards, and I was really happy with the book as a whole. I would definitely recommend it!
