When two sets of Sydney twins stumble upon a glowing fissure in the sandstone cliffs, they fall through time into the raw, perilous world of 1789, a colony on the edge of survival. Convicts labour under the lash, soldiers guard a settlement built on fear, and the land itself hums with ancient power. Raphaël and Anaïs together with Jonas and Johanna must navigate a world where loyalty can cost everything and courage means defying history itself. Guided by Nanduwara, a Gadigal man who understands the heartbeat of the earth, they uncover a secret older than the colony, a crossing between worlds that binds past and present. As storms gather and the fissure awakens, the siblings face a choice: return home or protect the fragile balance between two centuries. A Journey Back to 1789 is a sweeping tale of time, truth, and the land’s memory, where every step echoes across generations and every choice leaves a mark on history.
