Psychotherapist Gray ( What You Feel You Can Heal ) adds to the growing number of self-help books that assess marital and relationship problems in terms of distinct and pervasive gender differences. Unfortunately, his overuse of gimmicky, often silly analogies and metaphors makes his otherwise down-to-earth guide hard to take seriously. Here Martians (men) play Mr. Fix-It while Venusians (women) run the Home-Improvement Committee; when upset, Martians "go to their caves" (to sort things out alone) while Venusians "go to the well" (for emotional cleansing). While graphically illustrative, the hyperbolic, overextended comparisons, particularly in the chapters that refer to men as rubber bands and women as waves, significantly detract from Gray\'s realistic insights.
