He believes in science, but only magic can help his mom. Twelve-year-old Finn is used to people in his family disappearing. His twin sister, Faith, drowned when they were three years old. A few months ago, his mom abandoned him and his dad with no explanation. Finn clings to the concrete facts in his physics books—and to his best friend, Gabi—to ward off his sadness. But then his grandmother tells him a secret: the women in their family are Travelers, able to move back and forth in time. Finn's mom is trapped somewhere in the timeline, and she's left Finn a portal to find her. But to succeed, he'll have to put his trust in something bigger than logic. "This is an incredible book, no matter which time universe you're in. I couldn't put it down. One of my favorite debut novels of the year."—Erin Entrada Kelly, New York Times bestselling author and 2018 Newbery Medal winner

More than 400 films and 150 television series have featured time travel--stories of rewriting history, lovers separated by centuries, journeys to the past or the (often dystopian) future. This book examines some of the roles time travel plays on screen in science fiction and fantasy. Plot synopses and credits are listed for films and TV series from England, Canada, the UK and Japan, as well as for TV and films from elsewhere in the world. Tropes and plot elements are highlighted. The author discusses philosophical questions about time travel, such as the logic of timelines, causality (what's to keep time-travelers from jumping back and correcting every mistake?) and morality (if you correct a mistake, are you still guilty of it?).

This never-before-seen twist on time travel adventure explores the theme of accepting those who are different--and having the courage to join them. The moment Ambrose Brody steps into a fortune-teller's tent, he is whisked into a quest that spans millennia with his best friend, an enigmatic carnival girl, and an unusual family heirloom that drops them into the middle of the nineteenth century! The year 1852 is a dangerous time for three non-white children, and they must work together to dodge slave-catchers and save ancestors from certain death--all while figuring out how to get back to the future. Fortunately, they have a guide in the helpful hints embedded in an ancient Chinese text called the I-Ching, which they interpret using Morse Code. But how can a three-thousand-year-old book be sending messages into the future through a code developed in the 1830s? Find out in this mind-bending, time-bending adventure!

Best Books of 2016 BOSTON GLOBE * THE ATLANTIC From the acclaimed bestselling author of The Information and Chaos comes this enthralling history of time travel—a concept that has preoccupied physicists and storytellers over the course of the last century. James Gleick delivers a mind-bending exploration of time travel—from its origins in literature and science to its influence on our understanding of time itself. Gleick vividly explores physics, technology, philosophy, and art as each relates to time travel and tells the story of the concept's cultural evolutions—from H.G. Wells to Doctor Who, from Proust to Woody Allen. He takes a close look at the porous boundary between science fiction and modern physics, and, finally, delves into what it all means in our own moment in time—the world of the instantaneous, with its all-consuming present and vanishing future.

From H.G. Wells to Isaac Asimov to Ursula K. Le Guin, time travel has long been a favorite topic and plot device in tales of science fiction and fantasy. But as any true SF fan knows, astounding stories about traversing alternate universes and swimming the tides of time demand plausible science. That’s just what Paul J. Nahin’s guide provides. An engineer, physicist, and published science fiction writer, Nahin is uniquely qualified to explain the ins and outs of how to spin such complex theories as worm holes, singularity, and relativity into scientifically sound fiction. First published in 1997, this fast-paced book discusses the common and not-so-common time-travel devices science fiction writers have used over the years, assesses which would theoretically work and which would not, and provides scientific insight inventive authors can use to find their own way forward or backward in time. From hyperspace and faster-than-light travel to causal loops and the uncertainty principle and beyond, Nahin’s equation-free romp across time will help writers send their characters to the past or future in an entertaining, logical, and scientific way. If you ever wanted to set up the latest and greatest grandfather paradox—or just wanted to know if the time-bending events in the latest pulp you read could ever happen—then this book is for you.
