They crossed the mountains. They walked through time. Now they must protect the truth. When a modern research team is pulled through a shimmering fissure beneath Sydney, they land in 1813, on the eve of one of Australia’s most defining journeys. Forced to travel alongside Blaxland, Lawson and Wentworth, they witness the peril, courage and conflict behind the first crossing of the Blue Mountains. But the land is alive. The fissure is unstable. And history is not what they thought. Guided by Nanduwara, a man who walks between worlds, the travellers must survive storms, sacred valleys, collapsing ridges and the shifting river of time itself. Their mission is not to change history… but to save those who made it. Some stories are written in ink. Others are written in Country. And some must be carried by those who remember.
