Jo Swinney is the daughter of Peter and Miranda Harris, founders of the international movement A Rocha, which now operates in 20 countries including the UK. She is also goddaughter to our author Murray Watts. She has studied theology (MA in Christian Studies from Regent College, Vancouver, on top of a degree in English and African studies) and is a committed Christian - and a depressive, who has wrestled with her condition for some years. She still only in her mid-20s, which is the real USP for this book. Most authors on this topic are in middle life. There is a strong narrative thread running through the book, which again will appeal to a younger readership.
