On the first day of seventh grade, Rex encounters a bump in the road -- a big angry pimple right in the center of his forehead. And this is only the beginning of his problems. What follows is a frustrating battle with stubborn acne, body odor, and other embarrassments of puberty. Still struggling with a home life edging on the poverty line, Rex can't afford to buy the acne medication or deodorant he needs, and bullies are noticing Rex's awkward transformation. On top of it all, things have gotten weird with his friends, making Rex feel like he can't do or say anything right. So far, seventh grade stinks!
