If Henry Hart's buddies knew what he did after school, he would be the most popular kid in eighth grade. Henry lands a part-time job as Kid Danger, a sidekick-in-training to super-crimefighter Captain Man. The perks are awesome: $9 an hour, high-tech gadgets to use and -- best of all -- Henry gets to save the world! Yet he must keep the gig secret from his best friends, Charlotte and Jasper, and little sister, Piper, even as adventures with Captain Man throw Henry's life absurdly out of whack.
