This is the puberty book written by the cool, older brother—that takes boys from their first armpit hair to their first wet dream—and beyond.

Facts about developmental changes to tween and teen boys' bodies and brains are spelled out in fun, familiar, boy-speak and illustrated in edgy graphic novel format. So boys 10 and up can learn about health, hygiene, sexuality, and more in a way that's not embarrassing or tedious, but real, engaging, and enlightening. A recurring "Puberty Goggles" feature pokes gentle fun at the way a testosterone-tormented tween views himself and the world around him. The book also explores current hot-button topics from social media and cyberbullying to respecting women.
