The adventures of three curious boys who are transported back to dramatically different places in history.
Frankenstein's Monster has escaped from Mary Shelley's imagination and is wreaking havoc in Joe's apartment in Brooklyn! Joe, Sam and Jodie warp the monster back to Switzerland in 1816 and endure ghost stories and vampires in order to turn fact back to fiction!
Jodie and Freddi take Joe back to 1503 Italy to rescue famous Renaissance artist and inventor Leonardo Da Vinci from a showdown with Mad Jack, if they can escape the clutches of the ruling Borgia family and their infamous adviser, Machiavelli.
Though it's a very hot day, warping back to ice cold Antarctica in 1911 isn't exactly what Joe, Sam and Fred had in mind. There they encounter Robert Scott's Antarctic expedition, endure 47 degree below zero weather, eat hoosh (seal meat) and discover that Mad Jack has brought them to the one place on earth that's too cold for The Book to work!
The girls hear a mysterious radio transmission-and Freddi recognizes that it's the voice of her heroine, aviation pioneer Amelia Earhart, broadcasting an urgent message on her last, ill-fated flight. The girls warp back to 1937 and try to solve the mystery of Amelia's disappearance on her attempted around-the-world flight.
Jodie, Sam and Fred warp to the Topkapi Palace in the Ottoman Empire during the 16th century, they meet Selim, Suleiman the Magnificent's son, and his wily monkey, Dimples! The kids find themselves in a race through the palace and up to the top of a minaret with a crazed Dimples who suddenly starts wielding a scimitar and looking and sounding an awful lot like Mad Jack!
Joe, Anna and Jodie are on a wild ride-flung from a trebuchet and hurtling towards Castle Dunbar in Scotland during a siege in 1338 by the English Earl of Salisbury. But when the kids meet Uncle Joe in the dungeon they realize much more is at stake. Family conflict takes on a whole new meaning when Joe has to watch Uncle Joe and Uncle Mad Jack battle it out over the fate of the universe!
