Future Indefinite 

In a place called Nextdoor–the farthest flung outpost of British imperialism–earthborn mortals possess the power of gods. Young Englishman Edward Exeter has spent five years trying to escape the magnetic and powerfully magical pull of The Great Game which has designated him as its most important player. But war and bloodthirsty intrigues rage on both sides of magical portals and across worlds and Exeter can resist his destiny no longer. He accepts the mantle of Liberator that has been thrust upon him and the decision turns old friends into foes and old enemies into acolytes as he is surrounded by murderous plots and betrayals But this is not the uninformed Edward Exeter who came naked into this hidden realm years ago. He has lived the Game and learned it well–and he intends to play it boldly to its shocking, worlds-shattering conclusion.
