The less-than-innocents abroad in these daring short novels are Americans in Europe, involved in what turn out to be pleasure tours of hell: shocking, bewildering trips that change forever their ideas about history, reality, politics, sex - their entire lives. In the title novella, Landau, a third-rate American playwright, attends a literary conference in Prague, where an organized group excursion to a former concentration camp degenerates into a battle of wills and an exercise in egomania and public humiliation. Nina, the heroine of the second novella, "Three Pigs in Five Days, " is sent to Paris to write an article for her lover's travel journal - a dizzying, erotic pilgrimage that forces her to see how sex has distorted her view of the world.
