I actually just finished it and whizzed right through it. *I read A TON and judge a book on how well it held my interest. I thought it was well written (she is a writer and has been published in other genres) and easy to read.
As far as the content. . . do I think her parenting was extreme? Maybe, but it's not my place to judge. I'm sure I've done and said things that my friends and family wouldn't or didn't agree with. We have friends who over indulge their teen daughters, (brand new Volvo for 16th birthday, clothes from high end department stores etc.). I don't agree with that, but we are friends and it seems to work for their family.
Reading the book did make me think of the kids my daughter goes to school with. She is in a private school that is very culturally diverse. My daughter is extremely smart, wanting to study International Business at Stanford. BUT, the top 10% of her class are the Asian and Middle Eastern Students. Who, when I thought about it, reading the book, do NOT participate in the school plays, do NOT do anything extra outside of school but study. My daughter recently lost a team-mate off of the softball team because the girl's parents refused to let her practice normal team practices because she needed to study for the ACT. She had already taken it 2-3 times, but she had not yet gotten that perfect score of 36!
There are things I look back now with my kids that I wish I would have pushed harder, but we all do the best we can with the background and information we have. My kids won't be performing in Carnegie Hall, but I am extremely proud of them and their accomplishments!
Amy Chua, never really says "American Parenting" in the book. That I can remember. I'd look it up real quick, but have already loaned it out. But often refers to Western Parenting.
