My Grandpa, the Bodybuilder

Luqman Fields, a clever and witty fourth grader, has got the brains, but does he have what it takes to outwit bullies at school and at home? Tired of taking the cowardly way out, he just wants to defend himself. But self-defense is one thing, and showing off is another. Luqman has a crush on a girl in his class named Sophie. Dazzled by her smile and ability to play soccer better than all the boys, he'll do anything to impress her. He knows just the guy who can help him get it all done, but how much convincing will it take to have him on his side?
