Joe, Fred, and Sam, the Time Warp Trio, should know better by now than to mess around with The Book--a magical book given to Joe by his uncle. But this time they really think they have things under control... until Sam's latest invention, the Graphi-Sonic, accidentally interfaces with The Book, and the boys wind up traveling back in time to 1877. At least they recognize the turf--it's still their hometown of Brooklyn, minus the cars and skyscrapers. And plus one very addled Thomas Edison. Not to mention the trio's great-granddaughters from the future, who have (still with us?) inherited The Book. Now, all they have to do is find The Book (which is missing again) and skedaddle back to the future before the phonograph and light bulb and Edison's other inventions lose their chance of being invented. The many fans of Jon Scieszka's Time Warp Trio sequence (2095, etc.) will be thrilled to delve into another illogical, madcap, even slightly educational adventure with the hapless time-traveling lads.
