The Plot Against America by Philip Roth
In 1940 Charles A. Lindbergh, heroic aviator and rabid isolationist, is elected President. Shortly thereafter, he negotiates a cordial "understanding" with Adolf Hitler, accepting his conquest of Europe and anti-Semitic policies, and igniting a storm of fear for Jewish families throughout America. For one boy growing up in Newark, Lindbergh's election is first in a series of ruptures that threatens to destroy his small, safe corner of America and with it, his mother, his father, and his older brother.
...a brilliantly telling and disturbing historical prism by which to refract the American psyche as it pertains to war... - Booklist

Leviathan by Scott Westerfeld
Prince Aleksander, would-be heir to the Austro-Hungarian throne, is on the run. His own people have turned on him. His title is worthless.
