The Longest Road. The House of Stuart Sequence, #9

As the 1920s open, Denmark has fallen; Scandinavia and the whole of Northern Europe are under Russian occupation. The Baltic is a completely Russian lake. The newly-established Turkish Republic has lost its last foothold in Europe and Great Britain faces airborne and amphibious assault across the North Sea. In Asia however, Russia continues to lose ground. India becomes part of the Stuart Empire and, although this acquisition has been without bloodshed, nationalist aspirations soon arise across the sub-Continent.
As the Stuarts approach the bi-Centenary of their restoration to the British throne, it is clear that the longest road will be that leading to international peace. This is the long-awaited final part of the nine-volume "House of Stuart Sequence" of alternative history.
