I bought the book for a friend, and read it myself to see what the author had to say about life in the USA (I am American). I thought her writing style was strange; it was written like it was written by a foreigner, yet the author claimed she was native Californian. I had the impression it was written by someone from England. She used UK spelling everywhere. Many words are spelled differently between UK and USA. Why would anyone want to introduce someone to the US using UK words?
I also took exception to some of her left-wing views presented as "facts", particularly anything to do with crime and firearms.
Overall, I'd say the book was OK, but not great. It did present some of the pecularities of life in the US, but it could have been better.
