Girl Defined: God’s Radical Design for Beauty, Feminity, and Identity by Kristen Clark and Bethany Baird is a book that focuses on women’s self-worth. I think that the target audience would be girls in their teens or early twenties. The authors discuss societal beauty standards and how many women often feel like they are not “enough,” and then suggests ways that women can embrace their value and identity through Christ. The book sends a healthy, positive message, reminding girls that their true worth does not lie in external beauty, relationships, or even their careers. I especially liked the discussion questions at the end of each chapter, which encourage readers to share their thoughts regarding beauty and self-image. The authors are sisters, and since Clark is married and Baird is single, they both provide interesting perspectives on how women can serve Christ in their particular stage of life.
