One of today's most beloved picture book creators, Oliver Jeffers, opens up with a personal, gently funny letter to his own son—and in turn, to children and parents everywhere. Part guide to Earth's terrain (bumpy, sharp, wet), part meditation on our place in the universe (it's big), and part introduction to humanity (we're all people, despite appearances), this is Jeffers' user's guide to life on our planet. Sweet, funny, and quietly profound, it blends his signature wit with a warm message of kindness and tolerance—a must-have for parents and kids alike.
