With more than sixty moveable parts, the spectacular Ultimate Book of Vehicles presents a plethora of things that roll, float, fly, dig, demolish, and more. Help a construction worker climb a tall crane ladder and get into the cab, tip out a dump truck's heavy load, operate the scissor lift to elevate a window washer, and so much more! And for budding geologists, The Ultimate Book of Planet Earth presents our fascinating planet in fabulous 3-D details. Both books are recommended for ages 5 and up (but my three-year-old has loved his copies to shreds!).
