This is one of those relaxed but unoriginal books that attempts to reassure women in their thirties. The late author based many of her assumptions and conclusions on results of 1000+ questionnaires distributed coast-to-coast by women's organizations as varied as NOW and the YWCA, plus several hundred personal interviews. One wonders--especially in the absence of hard statistics here--whether many of the topics aren't as easily related to other age groups: is the move to lesbianism really more likely to occur in the third decade of life, for example? (Not very convincingly, disillusionment with the prior pursuit of matrimony and motherhood is blamed.) And the discussion of motherhood contains many topics that relate more to general problems of raising a child in the social climate of the Eighties than to motherhood after 30. Furthermore, some of Pellegrino's conclusions sound dangerously close to pigeonholing (""The over-thirty single woman. . . wants to feast her eyes on the loving smile on a little face""), while the indisputably relevant issues receive all-too-predictable treatment (the standard caution against falling prey to the superwoman trap, the assertion that single women can survive social pressure to be happily, productively independent). All in all, a not-very-distinguished study--though it might well provide some comfort to those cut off from any form of peer support.
