Welcome to the Amazing Automated Inn, home of twelve-year-old inventor Wally Kennewickett, his genius scientist parents, and his dashing dog, Noodles. From the lightning harvester on the roof to the labs full of experiments in the dungeon, the inn is a wonderful place for a curious boy and his loyal dog to live. That is, until President Theodore Roosevelt himself calls the elder Kennewicketts away, leaving Wally and Noodles to face the evil Mesmers, horrible hypnotists bent on controlling the minds of powerful people. It seems the inn is their first stop on the way to world domination . . . and only an ingenious boy, a staff of automatons, and a brave dachshund stand in their way!

Someone is smuggling secrets out of the Kennewicketts' lab and sabotaging their experiments, putting everyone at the Amazing Automated Inn at risk. In pursuit of the villains, the family of scientific geniuses board their dirigible and take to the skies. Together with their robotic staff and the inventor Nikola Tesla, they must face murderous sky pirates, cross the Alps in a giant mechanical spider, and defy the perilous pigeon Iron Claw and the malevolent magician Madini once more. Will boy inventor Wally and his daring dog, Noodles, be able to defeat the evil Mesmers and their minions a second time? History and technology collide in this fast-paced series narrated by a daring dachshund and brimming with mad science.
