Even though the adjustment of young people from various American Indian cultures to the white man's world is an old theme, the story of Martha Weekoty in her alien setting [Season of the Two-Heart] compels interest. At once proud of her Pueblo Indian heritage and impatient with the indifference of her family to new ways that would serve the well-being of her people. Martha hoped to reconcile the two ways of life…. [She soon realizes] that she would never serve her people by renouncing her chances for a university education and following the pattern her parents expected of her. Sharply contrasted with her own home, in which attention to the children's diets may have been lacking but attention to their emotional needs was abundant, was her home with the Boyntons in Albuquerque, where she lived and worked during her last year of high school. Much as Martha loved little Daniel Boynton she resented giving him the care he should have received from his mother. The several threads of plot are woven together in a convincing and moving climax.
