When Sheehy, author of the classic Passages ( LJ 5/15/76) and The Man Who Changed the World: The Lives of Mikhail S. Gorbachev ( LJ 12/90), wrote about her personal experience with menopause in the October 1991 issue of Vanity Fair , the response from readers was overwhelming and compelled her to expand the article into this surprisingly slim book. Interviewing over 100 women in various stages of menopause and 75 experts, she examines the medical, psychological, and social aspects of this ``silent passage.'' A biological change that spans five to seven years, this ``second adulthood,'' according to Sheehy, has three stages: perimenopause, menopause, and coalescence. While Sheehy performs a valuable service in bringing this topic out into the open, her book is weakened by her cliched Cosmopolitan -style prose and New Age psychobabble. Still, with the older members of the Baby Boom generation entering menopause, there will be demand for this book. Readers seeking practical advice should consult Winnifred Cutler and Celso-Ramon Garcia's Menopause ( LJ 11/1/91). Previewed in Prepub Alert, LJ 12/91.-- Wilda Williams, ``Library Journal''
