It seems like people who have read the book are split - either it's one that they enjoy and laugh as they read...while others can't even finish the book. So, I'm not sure what to expect.
According to some reviews on Amazon.com, the book is not about learning about Mennonite culture and beliefs, though there are mentions of what life is like in a Mennonite community.
The book is actually a personal memoir about how a series of unfortunate incidents brought the author back home. Rhoda Janzen addresses some rather sad and serious issues with style and humor that makes the book captivating and easy to read.
The author weaves childhood memories with anecdotes from the months spent visiting her parents (her father who is "the Mennonite equivalent of the Pope" and mother who is a pragmatic nurse and eternal optimist); her friends and family; and the Mennonite culture.
As the memoir progresses, the author shares her recovery (of roots and self) from her mentally ill husband and their failed marriage.
After I'm done reading the book, I'll come back and note whether I enjoyed reading it or not. It certainly is a departure from what I've been reading recently.
