Convinced that depression can be treated with therapy rather than just held in stasis for the eternal profit of drug companies, Greenberg (psychology, York U., Toronto) and Watson (adult education, community development, and counseling psychology; U. of Toronto) present a treatment approach that focuses primarily on intervening at the emotional level of the system. Occurring as it does as the interface between body and mind, they say, this level is highly influential and able to affect the system as a whole in important ways. They write for practitioners rather than theorists. Annotation ©2005 Book News, Inc., Portland, OR (booknews.com)
