Gaijin at the Gates: Book 5 of the American War

Four hundred miles of cold water. That is all that stands between America and Tokyo now.

November 1943. The bargains struck with a Soviet Union fighting for its life have bought the United States something nobody expected: ground in the north. From the airfields of Karafuto, American fighters can reach the Japanese capital and come home.

In Scammon, Kansas, a rotary gun built in a family barn is about to become the most argued-over weapon in the Army. Lightning Jack Gibson measures every mission in miles and fuel, because from the Marianas no fighter on earth can reach Tokyo. And in Japan, the last instructors and the last aces are gathered into one final squadron, handed the finest fighter their nation ever built, and ordered to fly until they die.

In Washington, a paper is being drafted that will decide what Japan keeps. One line in it names Hokkaido.

The war has reached the gates. Now someone has to decide what lies beyond them.

GAIJIN AT THE GATES is Book Five of The American War, a companion to The European War. Both series stand alone. Both converge.
