Her scathing review of “American Dirt,” in which she accuses Cummins of appropriating works by Latinos, went viral. “American Dirt,” published last week, tells the story of a Mexican woman and her 8-year-old son fleeing to the U.S. border after a drug cartel kills the rest of their family. Some Latino celebrities posted selfies with the book; Mexican-born actress Salma Hayek later apologized for promoting “American Dirt” without having read it after she was attacked on social media. Latino critics say ``American Dirt'' contains stereotypes, incorrect regional slang, and cultural inaccuracies. Tony Diaz, a Mexican American novelist in Houston, had promised to organize a protest outside.
