I bought this book for my ex-partner (we still get along!), it arrived to today and I thought I'd read just to check I hadn't bought something daft. I've read the first couple of chapters and so far I feel the language and communication are great. One of my worries was that it was going to sound too American, which would be a turn off for my ex, but it doesn't .
The main reason I wanted to add a review is that in the first chapter it asks you to supplement your work in the book with reading from another of his books - The Feeling Good Handbook - which happily I'd ordered anyway, but thought may be disappointing to get yourself in the mindset to read and DO the exercises in this book, only to find you didn't have all you needed. Perhaps it says that somewhere and I've missed it! But thought would be handy just in case.
