Rachel Jankovic wants teenage daughters to be a different kind of woman — genuine threats to the enemies of God, fair as the moon and terrible as an army with banners. In No Time to Be Dumb, she writes directly to teenage girls about the things that matter most, covering expected topics like modesty, peer pressure, emotions, body image, and boys, while also speaking candidly to harder questions about physical boundaries and pornography. With warmth, humor, and biblical conviction, Jankovic calls young women to spend their days pursuing wisdom and virtue rather than wasting them on sin and distraction. The book's central message is as straightforward as its title: you can't afford the time that stupid sin will take. Young women have all the time in the world for good things, but they really just don't have time to be dumb. A companion study guide with 64 chapter questions and 48 Scripture-comparison questions is available separately.
