One jump to save all 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. A Viking horde is ravaging England in the north while a Norman army threatens to invade from the south. In between and desperately struggling to hold on to his throne is Harold Godwinson, the newly-crowned English king. Dan is fighting to ensure that events play out correctly when he finds himself plunged into an even more lethal conflict. To save history, Dan must battle a band of malevolent time jumpers whose lust for wealth and power threatens the entire future of the world.

Every second counts in the fight to save all time.



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. As two Roman legions—intent on wiping out everyone on the island—draw closer, time is running out for Dan and Sam.

With Victor Stahl’s plot to rule the world on an unstoppable path in the present, seventeen-year-old time jumper Dan Renfrew and his partner Sam realize that their only hope of putting an end to Victor’s scheme is to jump into the past again. They arrive in Greece in the year 480 BCE just before the legendary Battle of Thermopylae, where a heavily outnumbered force of Spartan warriors and their Greek allies bravely try to prevent Greece from being overrun by the invading Persian army. But when a horrible accident happens in the past, Dan and Sam discover that Victor’s plot is the least of their worries.
