Relient K & Mark Nichols 
Complex Infrastructure Known as the Female Mind 
According to Relient K

In The Complex Infrastructure Known as the Female Mind, Relient K expounds on their experiences observing the opposite sex. Detailing some of the "girl types" they’ve encountered–like the Homecoming Queen, The Athlete, and The Overachiever–they share personal stories and biblical advice for girls of any type to become women of God. The band’s fun attitude is present throughout the book in quizzes, lists, personal stories, and more!
