Caroline Carr's book follows her own story of coping with a partner who gradually slid into depression and - eventually - came out of it again. Although their relationship was changed, it survived, and she describes how she felt and the strategies she used to cope. She has talked to many other people whose partners have suffered from depression and she uses these as case studies throughout the book. She also gives a mass of practical advice, some she used at the time and some learnt later, to help others going through the same stressful experience.
