About This Book
Reach for this book when your child starts asking what happens to the water in the drain, where the subway goes, or how deep a rabbit hole actually reaches. This lift-the-flap volume is designed for children who are beginning to look past the surface of things and want to understand the invisible systems and histories that support our daily lives. It transforms the literal ground beneath their feet into a layered world of discovery. The book moves from the familiar urban world of pipes and tunnels down through archaeological layers of fossils and eventually to the molten core of the planet. While primarily educational, it fosters a profound sense of wonder and spatial awareness. It is perfect for children aged 5 to 8 who are moving from simple picture books to more complex, detail-oriented nonfiction. It validates their curiosity about the hidden world and encourages them to imagine the 'invisible' parts of their environment.
