It all begins when Freddy Funkhauser, an off-beat nine-year-old with a knack for science, embarks on an ambitious plan to win new customers for the family business, The Burger Castle. But when his secret invention ends up working better than he'd ever dreamed, his plans go wildly awry as his kooky companions wreak havoc in every corner of Freddy's world.

David Baldacci now turns his tremendous thrill-creating talent to side-splitting storytelling in this hilarious adventure for middle-grade readers about fame, friends, and family.
