Take Monkey, a literary genius with flatulence; Bean, a science and math guru; Vinny, a computer whiz who can't keep her mouth shut; and Art, an artist who can shoot a basketball like a pro, confront them with a mess of fourth grade trouble, and watch the fun explode.

In book 3 of the Smartboys Club, the Smartboys get a mysterious new class member. She has a secret, and Monkey is bent on finding out the truth about her. But the Smartboys are in for a surprise when their class takes a suit-and-tie field trip to Symphony Hall, no burping allowed.
