Rachel Jankovic wants terrible teenage daughters. Not a wasting-her-time-in-petty-squabbles, doomscrolling, dumb television shows, eating disorders, and foolish crushes kind of terrible. But a different kind of terrible: to be women who are genuine threats to the enemies of God, "fair as the moon . . . and terrible as an army with banners" (Song 6:10). She is not easily controlled by flattery; her joy is in the Lord. She is growing from a girl you love into a woman you admire. In this book Rachel covers the topics you would expect, like Modesty and Homemaking and Boys. But Rachel also speaks directly to awkward questions such as Handsiness and Pornography. There's even a chapter on how to deal with self-righteous church ladies. Young women have all the time in the world for good things, but they really just don't have time to be dumb.
