I bought this book never hearing of Sarah Newton and am so glad I did. I found this book not a moment too soon, as my daughter is 13 and I admit defeat in understanding her. Like all parents,we want the best, right? Well, honestly, this book has given me so much hope and confidance to do the right thing in 'coaching' my daughter through the teen years. I can't wait to put into practise all the practical tips given by the author. I wish I had read this book for my older children (too late now) but hopefully this will help me tame the alien I have now! There are loads of case studies, once you read some of them, you realise you don't have it too bad! There is even a chapter on step-children which is the reason I bought this book. It has given my partner and I new hope and a positive way forward in dealing with my daughters unacceptance of our situation. You won't regret buying this book, best money I've spent on a book in years.
