Stone Spring

by Stephen Baxter

Published 3 June 2010
Ten thousand years ago, a vast, fertile plain linked the British Isles to Europe. Home to a tribe of simple hunter-gatherers, Northland teems with nature's bounty, but is also subject to its whims. Fourteen-year-old Ana calls Northland home, but her world is changing. The air is warming, the ice is melting, and the seas are rising. One day Ana meets a traveler from a far-distant city called Jericho- a town that is protected by a wall. And she starts to imagine the impossible... So begins a colossal engineering project that will take decades: the building of a wall that stretches for hundreds of miles- a wall that becomes an act of defiance against the implacable forces of nature, and an act of devotion as the bones of the dead are added to it. A wall that will change the geography of the world. And its history.--From front jacket flap.

Bronze Summer

Centuries have passed. The wall that Ana's people built has long outlasted her and history has been changed. The British Isles are still one with the European mainland and Doggerland has become a vibrant and rich land. So rich that it has drawn the attention of the Greeks. An invasion is mounted and soon Greek Biremes are grinding ashore on a coastline we never knew and the world will be changed for ever. Stephen Baxter's new series catapults forward from pre-history into the ancient world and charts a new and wonderful story for our world. This is a superb example of Baxter's belief that anything is possible for mankind - even making a new world.

Iron Winter

by Stephen Baxter

Published 16 August 2012
"Many generations ago, the Wall was built to hold back the sea. A simple dam, it grew into a vast linear city, home to scholars, builders, and merchants. Northland's prosperity survived wars and unrest--and brought the whole of Europe together. But now darkness is falling. Days grow shorter, temperatures colder, and in the wake of long winters come famine, destruction, and terror. As a mass exodus to warmer climes threatens to fracture Northland, one man believes he can outwit the cold, and even salvage some scraps of the great civilization--before interminable gloom settles over the land; before the fires of war lay waste to an empire; before the ice comes..."--
