Reasonably enough: how to discover one's weak points, and avoid common disasters, in love relationships--by the author of The Making of an American Mistress and like others. Sands divides her formula for happiness into equal parts of self-knowledge (with the caveat, don't live for love); self-defense against the common traps of unhappy relationships (losing oneself to make another happy, expecting love to conquer all differences and problems); and positive considerations in building a future with another person (each one's goals are equally important, and so on). There are no revelations here, and there are some wild oversimplifications. (E.g., ""men and women use their brains differently. . . . The male brain is specialized, relying more on the right hemisphere. The female brain is not specialized. Women integrate both hemispheres. . . using the two simultaneously."") The Sands' audience will likely respond to these familiar counsels, one way or other.
