La Nostalgie heureuse is Amélie Nothomb's latest book. You may not know this but Amélie Nothomb is Belgian, and she lived in Japan at various stages of her life. I never lived in Japan myself but one of my best friends did. And I've always been fascinated by all things Japanese.
This book is the story of the author as she travels to Japan with a TV crew to film her journey as she meets significant people from her past (her minder when she was a small girl, her one-time boyfriend) and visits locations from her childhood (her school, etc.)
It was a pleasant book to read. And I probably will enjoy reading it again in future. But I can't say it was earth-shattering. Am I missing the point somewhere?
