I'm not really sure how to feel about this book. I do think that Turner should have chosen another title. Holding Her Head High implies to me that these women had reason to be ashamed of their single motherhood. Of the biographies I read (I didn't finish the last three), only one woman meets that criteria - and there were extenuating circumstances in her case as well (her abusive husband wouldn't grant her a divorce, so she left anyway and later lived with another man). That said, these women do have amazing stories to tell, and their lives can be used to encourage many women.
While the stories are interesting, the writing is rough. Turner learned the English grammar lesson that a series is "three or more things" well and EVERYTHING is "point A, point B, and point C". Many of her turns of phrase are awkward, and I found myself having to reread sentences to figure out exactly what she meant.
Still, Turner makes her point with these stories, and the book would make a good study for a women's Bible group.
