This robot has two eyes, two arms, and two legs, but what really makes him tick? Inside The Robot Book, Heather Brown answers that question within an interactive story that features actual working–and moving–parts. Gears and cogs are mounted on each illustration to keep little fingers and imaginations engaged.

While the junior engineer is tinkering away, parents will also be charmed by the story’s warm text, which reveals the true secret behind what makes our robot tick. Here’s a little hint: It isn’t a gear, or bolt, or some other mechanical part, it’s what’s in his heart that counts the most. Perfect for year-round gift-giving, the book will be packaged inside a protective poly-bag.
