Fierstein, author of such groundbreaking theatrical works about gays as Torch Song Trilogy and the book for La Cage aux Folles , turns his attention to the AIDS crisis. These three one-act plays are unconnected except in their exploration of the psychological ravages of the disease. Although none of the characters is actually ill, all have suffered radical changes in their relationships and view of the world; all find that the very concept of ``safe sex'' inhibits their ability to connect, not just sexually but also emotionally, with others. In dealing with a topical subject, Fierstein movingly depicts the age-old difficulties and joys of loving. Highly recommended. Susan Thach Dean, Chicago P.L.
