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