Detective brothers Frank and Joe work to debunk a time travel machine in the eighth book in the interactive Hardy Boys Clue Book series. Bayport Elementary is almost ready for the annual science fair—it’s all down to the final touches. Frank and Joe have collaborated on a detective helmet. It’s the perfect lie detector—just place it on a suspect’s head and the bells and whistles will tell you when they’re lying. But not everyone is as prepared for the big fair. Their good friend Phil has designed a time machine he calls the Time Warp Wonder. He just needs to figure out how it works first… Phil uses Chet’s hamster as a test subject. And the machine really does make the hamster disappear from the cafeteria! It’s just that Phil isn’t sure where the hamster went or how to get him back. Frank and Joe are not so sure the hamster went back in time. They have a feeling their Clue Book will be more help to Chet’s hamster than Phil’s calculations. But the brothers start questioning their instincts when they receive pictures of the hamster in different time periods; dressed as caveman with the dinosaurs, suited up in armor in the middle ages, in a top hat watching Abe Lincoln give a speech. Could Chet’s hamster really be traveling though time? It’s up to the Hardy Boys—and you—to find out!

We are obsessed with time. However hard we might try, it is almost impossible to spend even one day without the marker of a clock. But how much do we understand about time, and is it possible to retrain our brains and improve our relationship with it? Drawing on the latest research from the fields of psychology, neuroscience, and biology, and using original research on the way memory shapes our understanding of time, acclaimed writer and broadcaster Claudia Hammond delves into the mysteries of time perception. Along the way, she introduces us to an extraordinary array of colourful characters willing to go to great lengths in the interests of research, such as the French speleologist Michel, who spends two months in an ice cave in complete darkness. Time Warped shows us how to manage our time more efficiently, speed time up and slow it down at will, plan for the future with more accuracy, and, ultimately, use the warping of time to our own advantage.

Joe, Sam and Fred sail with Leif Erickson, meet his evil cousin, feast on whale blubber and try to find the Book which always disappears when it is needed most.
