Book excerpt: "Dreams of the Centaur" brings to light for the first time in fiction the tragic enslavement of the Yaqui Indians by Porfirio Diaz's regime at the turn of the last century. Through the lives of the Ducals--a Mexican family who has created a ranch out of the desert--this "Western saga brimming with the heart and soul of Mexico . . . is an extraordinarily rich novel" ("West Coast Review of Books").
