Query: A unique and much-needed book

Ms. Keena's book offers a unique and empathetic aid to anyone struggling with adolescent depression--as caretaker or patient. For therapist, parent or the depressed adolescent herself, it provides both left-brained and right-brained perspectives on this often hereditary disease. By alternating between clinical observations from her current counseling work, and creative writings from her own teen years, Keena gives us a window into the mind of the clinically depressed, at times offering some gems of poetic expression as well as tools for understanding. She also inspires us by showing how she survived the sometimes fatal disease in order to live a productive and happy adulthood.
