The epic story of one prehistoric girl's bid to change her future and the future of our world. This is alternate history at its most mindblowing.
8 000 years ago Europe was a very different place. England was linked to Holland by a massive swathe of land. Where the North Sea is now lay the landmass of Northland. And then came a period of global warming, a shifting of continents and, over a few short years, the sea rushed in and our history was set.
But what if the sea had been kept at bay? Brythony is a young girl who lives in Northland. Like all her people she is a hunter gatherer, her simple tools fashioned from flint cutting edges lodged in wood and animal bone. When the sea first encroaches on her land her people simply move. Brythony moves further travelling to Asia. Where she sees mankind's first walled cities. And gets an idea. What if you could build a wall to keep the sea out?
And so begins a colossal engineering project that will take decades...
