Read one way, this book focuses on what's up above us - clouds, stars,
the Sun and Moon, things that fly. Flip the book and read it the other
way to find out what's down beneath our feet - burrowing animals, the
Earth's crust, fossils, caves, the Earth's core.
Go star-spotting, find out about cave-dwelling creatures, and discover a
whole world of fascinating information. Future titles in the series will
include Night and Day and Land and Sea.
