A very good and friendly introduction into the world of ACT. I'm a child therapist, and I'm only just getting to know this kind of therapy - I've recently had a beginner's course in it, and am planning on applying more of this in my treatments. This is a good start, though I don't necessarily agree with all of it (I find the attitude 'your thoughts don't influence what you do at all' to be a little too simplistic) it's a great introduction nonetheless, and it's good to have a different perspective on the philosophy of ACT. The only thing working against it is that it's very, very beginner, and as a therapist it was sometimes a little slow. The best psychology books, IMHO, are perfect to read for both therapists and clients, and this wasn't that, which is why it gets only four stars. But I can definitely recommend this to (parents of) clients.
