"Egged on by a ground squirrel, a dog named Doug digs miles underground--taking a detour through the White House--until he returns home, goes to bed, and dreams of digging some more"--Provided by publisher.

Follow the developments of tunnels, as they have gone deeper underground, have travelled further and helped us transport people, energy and goods through engineering skill, design and ambition.

"From mining tunnels to the Channel Tunnel, this book explores how they are built, how they are used, and the engineer's job to build and plan for them."--Provided by publisher.

Old Man sends Dark Man into the tunnels to find and extinguish a magic flame, the Fire of Doom, an evil gateway for demons.

The Channel Tunnel is a terrific tunnel. It runs underwater! In Building the Channel Tunnel, young readers will find out more about this engineering marvel and how it was built.

"Twelve-year-old Granite "Gran" Flowerpetal has just moved from the sunny coast to a hilly inland town full of trouble and mystery. He feels unheard at home and invisible at school--and then there's the issue of the many buildings in town collapsing into the earth. What can be done? One person, Gran's intriguing but difficult-to-please classmate, Catalina Catalan, knows what to do. But she avoids Gran like the plague. Will she reveal what happens underground? Will she tell Gran about the Hollows? The Lifters? And how the town, and the world, might be saved?"--Dust jacket.

"Carefully leveled text and vibrant photographs introduce early readers to the science and engineering behind the Channel Tunnel. Includes infographics, an activity, glossary, and index"--Provided by the publisher.

In 1928, nine-year-old investigator Lottie and her friends try to save the British Museum from shuttering its doors by looking for a buried treasure in a secret tunnel beneath the museum, only to discover they must solve a series of puzzles to find the treasure as well as their way out of the maze of passageways.

Tunnels examines the engineering concepts that make these important structures possible.

"Explores the engineering challenges behind building tunnels, as well as the creative solutions found to overcome those challenges"--Provided by publisher.
