The Defeat of Agent Big Butt

What's a superhero without his powers? AB learns just that in "The Defeat of Agent Big Butt: Out of Gas", the second book in the "Agent Big Butt" series.

After the evil Dr. Ian kidnaps AB's mother, it's up to AB, Alex, and Theodore to sneak off in the middle of the night to rescue her. After a few bumpy starts (like a certain someone's butt getting stuck in his bedroom window), they race off to save his mom, and unbeknownst to them, straight into Dr. Ian's diabolical trap.

To further complicate his life, AB wakes one morning and discovers his butt is now flat as a pancake, all his superpowers completely gone. And as if that's not bad enough, there's a new super butt in town, and this butt is evil. Justin, AB's archenemy, now controls a giant-butt robot complete with all the stinking powers AB once had. Will our hero get his powers back and become the Master Blaster again, or will Justin, Dr. Ian, and his mutant sons finally get their chance to take over the world?
