When Jake is kidnapped by strangers on a stormy London night he discovers his loving parents have been leading a double life and are now missing, lost somewhere in history. He is plunged into a world of secret societies, dangerous double agents, and a terrifying countdown to oblivion. Transported by a Spanish galleon back to 19th century France, he finds himself in the headquarters of The History Keepers - a remarkable league of time-travelling special agents. The History Keepers preserve the true course of history against those who would change it for their own gain, such as the diabolical Prince Zeldt. Driven by a sense of adventure and a desire to reunite his family, Jake makes the most thrilling - and dangerous - decision of his life.
