Imagine if you lost your parents - not just in place, but in time.
Jake Djones' mum and dad have gone missing and they could be anywhere in the world - at any time in history. Because the Djones family have an astonishing secret, which for years they've managed to keep - even from each other. They belong to the HISTORY KEEPERS: a secret society which travels through the centuries to prevent evil enemies from meddling with History itself.
In the quest to find his parents, Jake is whisked from 21st Century London to 19th century France, the headquarters of the mysterious History Keepers, where he discovers the truth about his family's disappearance - and the diabolical Prince Zeldt's plan to destroy the world as we know it .
