The Lacuna contains two very distinct parts. One features a vibrant Mexican landscape with the equally colorful personalities of Rivera, Kahlo, and Trotsky. The other centers more on Harrison's reclusive existence in small-town America and his battle with the House Un-American Activities Committee. Despite the prodigious research that both parts exhibit, critics clearly preferred the former, marveling at Kingsolver's lyrical passages and her expert recreation of 1930s Mexico. A few reviewers also noted instances of sermonizing and inaccurate history. However, the novel's compelling, engrossing story certainly outweighed these minor complaints, and in the end, Kingsolver has created a convincing "tableau vivant of epochs and people that time has transformed almost past recognition.
