A Jump in Time

Life is progressing normally for sixteen-year-old Dan Renfrew when he accidentally transports himself to England in the year 1066. He soon realizes that he’s trapped there, and that’s not his only astonishing discovery. Dan learns that he’s descended from a long line of time jumpers—secret heroes who travel to the past and resolve glitches in the time stream that threaten to alter subsequent history. The only way Dan can return home is to set history back on its proper course in the Anglo-Saxon age. This is no easy task.

Dan Renfrew hates that he’s a time jumper—seventeen-year-olds should not be stuck with the responsibility of saving history. But with no one else stepping up to stop Victor Stahl’s plot to take over the world, Dan and his time-jumping partner Sam have no choice but to jump back into history again. They land on the Celtic island of Anglesey in 60 CE, hoping to find answers on how to stop Victor. Their task isn’t easy. Everyone seems to be hiding something, from the druids who rule Anglesey to the Celts who take the time jumpers in.

Seventeen-year-old Dan Renfrew's life is anything but ordinary. In addition to facing the usual teenage challenges, he has a secret. He's a time jumper, a member of a clandestine group tasked with fixing glitches in history. When rogue jumpers threaten global chaos, Dan and his partner Sam embark on a perilous mission to Mongolia in the year 1179. There they encounter a brave teen fighting to save his kidnapped wife. They soon realize they're in a desperate race against time to save the Mongol Empire—and the future of the entire world.

Seventeen-year-old Dan and his partner Sam know that their only chance to stop Victor Stahl’s quest for global domination is another jump into the past. This time, they find themselves in ancient Greece on the eve of one of history’s most famous conflicts: the Battle of Thermopylae. Heavily outnumbered by the massive Persian army, the Spartan warriors and their allies are girding themselves for war when a horrible accident threatens the fabric of history itself. In a race against time, Dan and Sam must battle to prevent a catastrophe far worse than Victor’s sinister plans.
