"Shy, unpopular Code is miserable when his grandfather disappears. His life goes from bad to bizarre when, on a school field trip, he trips over a hole and winds up in Mek Mound--once an ancient Okalahoman pyramid, now a land of metallic robots that threaten Earth. David Ackroyd's narration is solid and precise. He gives a human sound to a myriad of robot personalities--a windy-voiced curmudgeon of an inventor, Code's chatty robot buddy, and their threatening nemesis, Immortalis. Ackroyd delivers Code's fears and hopes, as well as moments of humor, as he searches for a way to free his grandfather and vanquish the mechanical villains. S.W. (c) AudioFile 2011, Portland, Maine"
