The author of this book suffered from bipolar disorder and attempted suicide. Her lucid account of the stages a sufferer undergoes made me think again at all those people who feel depressed and hopeless. I read it through with vivid expectation and deep respect and feel thankful for the comprehensiveness the author achieves. The matter is treated with academic insight and personal inward-looking that makes this book wonderfully attractive to everyone.
