Imagine if you lost your parents - not just in place, but in time.

Jake Djones’s 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.
