The final adventure in bestselling author Patrick Carman's delightfully wacky Floors trilogy



It's not every day that a hotel loses its top floor. Then again, the Whippet Hotel is no stranger to wackiness. So when the entire floor is hoisted into the night sky by a nearly invisible airship, Leo and Remi know they're in for the ride of their lives.



But little do the boys know just how amazing their voyage will become. They are headed to the field of wacky inventions, where they will have to compete against a number of foes for an incredible prize.



It will take all of Leo and Remi's bravery, skill, and burping power to decode the outrageous puzzles hidden among the floors of Merganzer D. Whippet's newest and most peculiar construction. But they must -- because if they don't, they'll lose their beloved Whippet Hotel forever.
