The proverbial teen-age heroine, described not as pretty, but possessed of miraculously slanting eyes, curly black hair, and a half dozen other such assets, roams through the cardboard maze of this novel. Jaqueline Gorda, newly arrived in California's Arroyo Verde High School finds adjustment a problem. Her work on a local paper, her involvement in a flood control crusade, a romance with an angry young man, and her general popularity soon serve to overcome her discomfort and she ends up pretty much as one would expect, given the familiar machinery of the plot--on top. A vivid feeling of locale and miscellaneous but interesting data on flood control and newspaper work give Tumbleweed Heart whatever distinction it can claim. By the author of Miracle of Sage Valley.
